I have had this problem for over a year now. My scrotum area and legs and stomach and sometime my underarms start itching around 4pm everyday. It felt like i had fiberglass under my skin. the sides of mt stomach would break out in a rash at times. I started out combating this with athletes foot spray, it took away the itching right away. I changed my bath soap, shampoo, and also laundry soap. None of that helped. So I then stopped drinking soda, for about 10 days with no difference. then milk and so on... Nothing stopped the itching. About 6 months ago i started taking allergy pills for it and that stopped the attacks. No w it seems as though the allergy pills no longer help because i feel this itching thing coming back. Today I was itching around my anal to scrotum area and i could feel something like a vein that hurt when i touched it. Now i am worried what this may be. And if this is the main cause from the itching

Thanks for posting your query.
Given your complaints, there are several possibilities that need to be considered
•     Hives or urticaria: Hives have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in same or other places after some time. They are mostly in response to allergens in the environment but can also occur to hot and cold conditions.
•     Fungal infection which can be ruled out after a potassium hydroxide (KOH) examination of the skin scrapings from the area.

The standard treatment of hives is oral antihistaminics like cetrizine, fexofenadine, diphenhydramine and topical steroids. Oral antihistaminics relieve itching and you can get them over the counter like you can tablet Cetrizine 10 mg once daily. However, some of them may cause drowsiness and hence should be taken under a medical guidance.
Topical steroids are available by prescription from a dermatologist but if it is a fungal infection then you may need topical antifungals. So diagnosis needs to be confirmed first whether it is due to hives or fungal infection.
I would suggest the following:
•     You can apply calamine lotion which will help in soothing the skin
•     Take plenty of Vitamin C which is a general anti-allergy supplement. It helps stabilize mast cells so they are less likely to release histamine. You can also take a diet XXXXXXX in vitamin C like citrus fruits, oranges, papaya, grapefruit, raspberries, blueberries, cranberries, and pineapple.
