Early symptoms of osteosarcoma

The early symptoms of osteosarcoma are generally not very obvious, manifesting only as occasional pain and discomfort around the joints, which can limit joint mobility. As the condition progresses, this intermittent pain becomes continuous. Additionally, the intensity of the pain gradually increases, and lumps may also appear, which typically cause pain when pressed. As the disease further advances, patients may also experience low-grade fever, anemia, and liver and kidney failure, eventually leading to pathological fractures. Therefore, for the treatment of osteosarcoma, early detection and early treatment are crucial for the best prognosis.

How long does lumbar muscle strain need to rest?

Generally speaking, for lumbar muscle strain, it is recommended to rest for three to four weeks. During this time, it is important to avoid strenuous activities and exhaustion to allow the symptoms of lumbar muscle strain to gradually alleviate. However, this type of lumbar muscle strain is due to chronic damage to the lumbar muscles. It is difficult to achieve complete healing through rest alone, and the healing time can be very long. It is possible that after resting for three to four weeks, the symptoms can be completely relieved, but symptoms such as back pain may recur after subsequent excessive exertion or intense exercise. Therefore, for patients with lumbar muscle strain, in addition to absolute rest, we also recommend using some physical therapy methods, such as massage and acupuncture, to help relieve back pain and promote the recovery of lumbar muscle injuries.

How to diagnose osteosarcoma?

For the examination of osteosarcoma, the first step is to take an X-ray, which can show changes in the bone quality. At the same time, it is necessary to perform a CT scan or MRI to clarify the nature of this bone tumor and its extent, or whether there is any distant metastasis. The third method is a nuclear bone scan, which mainly detects whether there are any early distant metastatic lesions. Of course, in clinical practice, the gold standard for diagnosing osteosarcoma relies on the examination of living tissue. That is, to perform a surgery, carry out a minor operation to obtain a little tissue from the bone tumor, and then send it for pathological examination to determine the nature of the tumor. This is the gold standard for diagnosing osteosarcoma.

How to prevent osteosarcoma

From the perspective of osteosarcoma itself, prevention should involve active exercise, a healthy lifestyle, and a regular schedule. All of these can play a preventive role. However, as of now, there is no clear cause of what triggers osteosarcoma, and it is still unknown. For patients with osteosarcoma, we need to achieve early diagnosis and early treatment. Since many osteosarcomas occur in adolescents, if your child complains of bone pain and feels lumps, and more severely, experiences joint functional impairment, parents must be vigilant. It is advised for the patient to go to a hospital and have an imaging test done to confirm if it is caused by osteosarcoma. Therefore, early diagnosis and early treatment are best.

Non-surgical treatment methods for lumbar disc herniation

Methods for non-surgical treatment of lumbar disc herniation currently include the following in clinical practice: The first is traction therapy, which can relieve pain and numbness in the lower back, though the effectiveness in alleviating numbness may not be very significant; The second is massage, which can also relieve symptoms of pain in the lower back; The third involves the use of topical plasters, such as non-steroidal anti-inflammatory and analgesic plasters, as well as plasters that activate blood circulation and dissipate blood stasis, to relieve localized pain; The fourth can be achieved through electrotherapy or magnetotherapy; The fifth is acupuncture. Currently, the application of acupuncture to relieve symptoms of lumbar disc herniation in clinical practice is quite evident; it has a better effect than traction. Additionally, oral medications that nourish the nerves are required because patients with lumbar disc herniation might have a protruded disc compressing the nerve roots, possibly causing nerve root damage. Therefore, it is also necessary to take certain nerve-nourishing medications orally to alleviate these symptoms.

Differences between bone hyperplasia and osteoporosis

Bone hyperplasia and osteoporosis are quite different. Firstly, bone hyperplasia occurs due to long-term stress and degeneration of joints, including the lumbar spine, causing the bones around the joints to harden and proliferate, forming bone spurs. On the other hand, osteoporosis mainly results from decalcification and calcium deficiency, leading to weakened or porous bones. These bones are brittle and can easily fracture under trauma. As for the treatment of these two diseases, conservative treatment is mainly used for bone hyperplasia, such as acupuncture, physiotherapy, massage, oral blood-activating and pain-relieving medications, to alleviate local symptoms. Treatment for osteoporosis primarily involves oral medications, such as calcium supplements and vitamin D3, along with exposure to sunlight. Of course, some patients suffer from osteoporosis due to long-term disuse, as seen in patients with hemiplegia who are unable to walk for extended periods, leading to disuse osteoporosis. These patients also need to strengthen their routine functional exercises, such as undergoing suitable rehabilitation to enhance bone strength.

Can tendinitis be cured?

Tenosynovitis is curable, and there are currently two clinical treatment methods for tenosynovitis. The first method is conservative treatment. The most important and main point of conservative treatment is rest. You can go to the hospital to have a plaster or brace made to protect and restrict the movement of the fingers and wrist. Secondly, you can take some non-steroidal anti-inflammatory and analgesic drugs orally to relieve local pain. Third, local pain points can also be injected with a block to relieve pain. However, the number of times block needle treatment can be used is limited to once or twice a month at most. Thirdly, local hot compressions can be applied to increase local blood circulation and thereby relieve local pain. If the above conservative treatments are ineffective and symptoms progressively worsen, surgical treatment can be pursued, which can completely cure tenosynovitis. (Please use medication under the guidance of a professional physician.)

Is it okay to swim every day with lumbar disc herniation?

Patients with lumbar disc herniation can swim because swimming is a non-weight-bearing exercise. While swimming, it appropriately exercises the muscles in the lower back area, thereby alleviating symptoms of lower back pain caused by lumbar disc herniation. It is crucial for all patients with lumbar disc herniation to avoid exercises that load the lower back, such as playing ball, running, marathon running, and weightlifting in the gym. These activities create vertical pressure that can exacerbate lumbar disc herniation, leading to nerve root damage and eventually requiring surgical intervention to alleviate the pain.

What are the symptoms of osteosarcoma recurrence?

The symptoms of recurrent osteosarcoma include the following points: Firstly, if osteosarcoma recurs, it can cause sudden severe pain in the affected limb. This pain tends to intensify as the disease progresses and may shift from intermittent pain to continuous pain. Secondly, there might be metastasis to the lungs or other parts of the body. In such cases, if lung metastasis occurs, the patient will experience significant chest tightness and breathing difficulties. Thirdly, recurrent osteosarcoma can also lead to weight loss, decreased appetite, and the occurrence of low-grade fever. Fourthly, if the tumor recurs, the patient’s joints and the affected limb's mobility will be significantly hindered, and this can also cause numbness in the affected limb.

Is it good to get a steroid injection for tenosynovitis?

Treating tenosynovitis with injections is acceptable. Injections can significantly alleviate the pain caused by tenosynovitis and symptoms of limited joint mobility. However, it is imperative to take precautions during this treatment. Firstly, the injection contains steroids and anesthetics, so the number of injections must be limited. Generally, it is advisable to administer it once or twice a month. Excessive injections should be avoided as they can damage the local tendons or even the tendon sheaths, potentially exacerbating the pain from tenosynovitis or leading to spontaneous tendon ruptures. Therefore, the frequency of injections should be limited to a maximum of one to two times per month. Secondly, it’s crucial to ensure proper disinfection of the area during injections to prevent infections at the injection site and attend to potential bacterial infections. (Use of medication should be under the guidance of a physician.)
