Is your itching symmetrical? By that I mean do both your wrists itch and then both your knees and then both your ankles, etc.?
Hello,
For this continuous itching, since there is no rash, pain or discharge, get it evaluated from a dermatologist and get a biopsy skin done. This will confirm the diagnosis. Till then, you should keep the area clean and apply some topical antiseptics. Also wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove. Avoid any kind of cosmetics and apply calamine lotion. You can take oral antihistaminics to get a relief from itching.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
