Hi, thanks for using Healthcare Magic. I understand your concern, but unfortunately, there are some information I need, such as: 1. How about the color 2. Is there any itching or pain in that area. Briefly, it might be Psoriasis. FYI, Psoriasis is an inflammatory disease of the skin that is chronic, where the sufferer undergoes a skin change that is too fast. This disease sometimes disappears, not life-threatening, but can reduce the quality of life because it can make sufferers become less confident if not treated properly. Psoriasis is not contagious but can be genetically inherited. The commonest triggers of psoriasis recurrence are stress and physical exhaustion. Therefore should avoid things that can trigger stress. Until now there is no drug that can cure psoriasis in total. All existing treatments can only suppress psoriasis symptoms, improve skin condition, relieve itching. Most patients never achieve a medication-free recovery condition so that psoriasis sufferers can not stop treatment. There is continued treatment as a long-term maintenance step to maintain the condition and also to control new skin disorders. Another thing to consider before choosing a treatment of psoriasis is the degree of severity suffered. Also the location of the disease, type, age and gender are also medical history of the patient. - The first step is done outside treatment (topical). This step can be done for patients with mild psoriasis with an area of ​​skin disorders less than 5 percent. Drugs that can be used include coal tar, corticosteroid, calcipotriol, antralim, topical retinoids (tazaroten), salicylic acid, pimecrolimus, emollients and keratolytics. - The second step or phototherapy is usually used to treat successful psoriasis with topical treatment. - The third step is systemic treatment, ie drugs that are eaten or inserted by injection. The drug will be absorbed and into the bloodstream then spread throughout the body. Medications that can be used include retinoids, methotrexate, cyclosporine, azatiophrine. I would like to suggest you to discuss it further with a dermatologist. Hope this helps. Take care,
