Plantar fasciitis is mostly caused by prolonged standing, such as wearing high heels or leather shoes for extended periods. The fascia remains tense under these conditions, leading to tenderness in the sole's fascia upon examination. Pain tends to intensify while walking or bearing weight and alleviates when resting as the fascia relaxes. It is best to diagnose and treat this condition early. Applying heat, reducing the movement of the affected limb, and avoiding tension in the fascia are advisable. Consuming medications that invigorate blood circulation and relieve pain can also help, generally improving symptoms within 7 to 10 days. Recovery might be slow in some cases due to fascial damage. Furthermore, repeated pulling or tension from standing and working can lead to recurrent episodes. Rest is recommended for such individuals, and wearing softer sports shoes during activities can be beneficial. Resting and taking blood-invigorating medications usually lead to gradual recovery. For severe cases ineffective with conservative treatment, surgical cutting of the fascia may be performed to relieve pain. (Please use medication under the guidance of a professional physician.)

Plantar Fasciitis Physical Therapy Methods

The most common clinical treatments for plantar fasciitis are, firstly, injection therapy, secondly, acupuncture, and thirdly, small needle knife therapy. Among these, injection therapy has the most noticeable effects, but it also has a significant problem. Since the injections contain steroids, excessive use of injection therapy can not only fail to alleviate symptoms but may actually damage the plantar fascia, leading to a worsening of plantar fasciitis symptoms. Therefore, it is crucial to limit the frequency of injection treatments to no more than once or twice a month. If the symptoms of plantar fasciitis do not improve significantly with physical therapy and the pain progressively worsens, then surgical treatment may be necessary. The goals of surgery are firstly to release the plantar fascia and secondly to remove bone spurs, thereby completely alleviating the symptoms of plantar fasciitis pain.

How long does it take to recover from plantar fasciitis?

For the disease of plantar fasciitis, if treated under normal conventional methods, the recovery time is generally around four to six weeks. However, during the treatment period, it is crucial to strictly follow the treatment principles, such as prohibiting excessive weight-bearing walking, strenuous exercise, and overworking. At the same time, some physical therapy methods should be coordinated, such as massage, acupuncture, electrotherapy, and magnetotherapy. In more severe cases, occlusion methods can be used to alleviate local pain. Generally, the time frame is four to six weeks. If the results from regular conservative treatment are not satisfactory, surgical treatment may be required later on.

Plantar fasciitis complications

It is possible that local scar healing occurs, which means that after a period of rest and treatment, the local inflammation in plantar fasciitis may heal with scarring. Therefore, continuing to walk and bear weight on the foot may initially result in some restricted movement or still be accompanied by local pain. It is advised to reduce unnecessary weight-bearing on the foot and continue local daily heat therapy. After a period of recuperation, the degree of restricted local movement will gradually improve. Other complications may still occur, including local pain, restricted movement, and swelling. These are mainly due to excessive local weight-bearing or wearing shoes that are too tight.

Plantar fasciitis symptoms

The main symptom of plantar fasciitis is pain on the inner side of the foot when bearing weight and walking, which severely affects weight-bearing walking. Over time, this pain during weight-bearing walking can turn into what is known as rest pain, which is pain in the foot even when it is not bearing weight. The treatment of plantar fasciitis is currently divided into two parts in clinical practice. The first part is conservative treatment, which mainly involves massage, acupuncture, electrotherapy, magnet therapy, and occlusive methods to relieve the symptoms of foot pain when bearing weight. If this conservative treatment is ineffective and the pain worsens, severely affecting weight-bearing walking, surgical treatment may be necessary. The goals of surgical treatment are, firstly, to release the plantar fascia, and secondly, to remove heel spurs, as a significant number of patients with plantar fasciitis also have heel spurs. Thus, the aim of surgery is to release the plantar fascia and remove the heel spur to alleviate the pain during weight-bearing walking.

Can you still exercise with plantar fasciitis?

Patients with plantar fasciitis can exercise, but there are definite restrictions on the type of exercise. For instance, it is best to avoid weight-bearing exercises such as running, weightlifting, or mountain climbing. For patients with plantar fasciitis, we recommend swimming because it involves limb, muscle, and fascia activities in a non-weight-bearing situation, which is greatly beneficial and not harmful to the fascia. Swimming is our recommended approach, as it can also appropriately stretch the plantar fascia during the process, thereby helping to alleviate foot pain.
