In the advanced stages of lower extremity varicose veins, fixed ulcers can appear above the ankle in certain specific areas. These ulcers may improve or worsen intermittently and are long-lasting. The ulcers might gradually enlarge, and pigmentation can occur around them, with the skin gradually darkening, and even turning black. If these ulcers continue to remain unhealed for an extended period, there is a possibility of cancerous changes in some individuals. Therefore, it is essential to treat lower extremity varicose veins that have progressed to ulcers, with the primary treatments being compression therapy and medication, which can also be combined with surgical treatment.

What does it mean when varicose veins occasionally have blocked blood flow?

The so-called varicose veins are caused by blood circulation blockages, which likely refers to local thrombus formation, leading to feelings of congestion in lower limbs, or caused by compression from above, such as tight clothing, exacerbating the obstruction of blood flow. This might result in increased surface tension of varicose veins in the lower extremities. Additionally, there might be some pain upon pressing, or even spontaneous pain. In such cases, differentiated treatment is required. For instance, if the issue is due to compressive clothing, like tight-knee socks or pants legs that are too tight, simply relieving the pressure should suffice. However, if a thrombus has formed causing increased local tension, pressing or massaging must be strictly avoided, as there is a risk the thrombus might dislodge and potentially lead to pulmonary embolism.

What should I do about varicocele?

The treatment methods for varicocele vary based on the severity of the condition. Clinically, some patients with varicocele show no obvious symptoms and it is only discovered during a physical examination. These patients can generally be observed temporarily, and can also wear tight underwear or use a scrotal support to alleviate the condition. However, some patients do exhibit clear symptoms, such as a significant sensation of heaviness in the scrotum, especially after standing or walking for long periods, where the pain becomes more pronounced. These patients generally need to consider surgical treatment, where the main procedure involves high ligation of the spermatic vein. This can help alleviate symptoms and also improve the quality of semen.

What are the symptoms of varicocele?

The symptoms of varicocele vary depending on the severity of the patient's condition. Clinically, most varicocele patients have no obvious symptoms or no symptoms at all, and varicocele is often discovered during physical examinations. A small percentage of varicocele patients exhibit noticeable symptoms. The primary symptom is a feeling of heaviness or discomfort in the testicles, especially after prolonged walking or standing. The pain becomes more pronounced, but it will decrease or even disappear after lying down and resting. Some varicocele patients may not show symptoms but present with infertility. Varicocele is then discovered through physical examinations or related medical tests.

What are the harms of varicose veins?

The harms of varicocele are mainly manifested in the following aspects. The first aspect is that varicocele causes a sensation of dragging pain in the testicles, affecting the patient's normal work and life. The second aspect is that due to the presence of varicocele, there is a decline in the quality of male semen, which affects male fertility. The third aspect is that if the varicocele is severe and persists for a long time, it may lead to testicular atrophy, resulting in a decrease in the level of testosterone secretion by the testicles, which reduces male sexual function. Therefore, patients with varicocele, especially those with decreased semen quality, should actively seek surgical treatment, which currently mainly involves high ligation of the spermatic vein.

What happens if varicose veins worsen?

Varicose veins, when they worsen, can lead to changes in the skin, including thickening of the skin which feels woody to the touch. Additionally, the skin may exhibit pigmentation that can be severe enough to resemble the black color of a belt. More seriously, ulcers can develop, typically near the inner ankle, though they occasionally appear in other locations. These ulcers are referred to medically as “boot ulcers” and are commonly known among the general population as “continuous sore legs.” In extreme cases, these ulcers may persist for many years without healing and could potentially become malignant.
