The thigh root is red and swollen with bloodshot

The groin is a very private area and not very obvious, so it is generally difficult to notice any abnormalities in this area. However, some people find that the groin is red, swollen and bloodshot. There may be a variety of reasons for this. The skin in this area is relatively thin, and the capillaries may be mistaken for red blood. In addition, consider whether the symptoms are caused by allergies, tinea cruris, etc.

Causes of Tinea Cruris

It is often caused by Epidermophyton floccosum, Trichophyton mentagrophytes, Trichophyton rubrum, etc. Sometimes, Candida albicans also invades the groin area and presents as erythematous desquamative patches with papulovesicles on the edges.

This disease is prone to occur in warm and humid seasons, and men with excessive sweating are particularly susceptible to it. People in special occupations, such as car drivers and those who sit for long periods of time, are also prone to the disease.

Clinical manifestations of tinea cruris

It often occurs on the skin of the thigh opposite the scrotum, on one side or both sides, and is mostly annular or semi-annular patches. Initially, a small patch of erythema appears on the inner side of the upper thigh, with desquamation on it, and gradually expands and spreads to the surrounding area with clear borders, and there are papules, blisters, scabs and itching on it. The central part can heal itself, with pigmentation or desquamation. Over time, the local skin will become infiltrated, thickened and lichenified, often accompanied by itching. In severe cases, it often extends to the inner thigh, perineum or around the anus, and the lower edge is usually clear. Sometimes it can affect the scrotum, base of the penis, etc.

Tinea cruris treatment

Obese people should take a bath frequently and apply face powder, etc.

Treat tinea corporis. Because the skin of the pubic area is more delicate, care should be taken not to use overly irritating lotions to avoid skin irritation. Generally, compound resorcinol ointment or 1% econazole or clotrimazole cream, 2% miconazole, bifonazole, ketoconazole, sertaconazole, butenafine, and terbinafine cream can also be used.

Oral griseofulvin has a certain therapeutic effect, but it is easy to relapse after stopping the drug and is not suitable for use. Fluconazole, itraconazole, terbinafine, etc. can be used in the short term.
