Hi,
I started like that 16 years ago. It turned out to be a perfume allergy. I would go to bed at night and the sheets would make me itchy. At first, I did not know what it was. I then realized it was fragrance. Every type bothered me. I cleaned my home out. Switched to a fragrance free laundry detergent. I washed everything, got rid of scented candles, anything that had a fragrance. It made me itchy to be around people with cologne/perfume on. Even your under arm deodorant, shampoo, conditioner, hand soap,dish soap. Go all fragrance free and see if that helps.
Hello,
Itchy skin that isn't accompanied by other obvious skin changes, such as a rash, is most often caused by dry skin (xerosis). Dry skin usually results from environmental factors that you can wholly or partially control. These include hot or cold weather with low humidity levels, long-term use of air conditioning or central heating, and washing or bathing too much.
Other conditions cause itchy skin as well. Skin conditions like psoriasis,dermatitis,lice,scabies and hives, internal diseases like liver and kidney disorders,diabetes, iron deficiency anemia, irritation and allergic reactions to chemicals,wool,soaps,cosmetics and certain foods can cause itchy skin.
In your case as it is after intercourse,so pls check whether your partner is wearing any perfume or cosmetic,hand or body wash or any condoms.
You can apply an anti-itch cream or lotion to the affected area. Oral antihistamine, such as Benadryl can also be used. You should take a comfortably cool bath and wear smooth-textured cotton clothing. Covering the affected area with bandages and dressings can help protect the skin and prevent scratching. You should choose mild soaps without dyes or perfumes and use a mild, unscented laundry detergent when washing clothes, towels and bedding.
Pls take a second opinion from a dermatologist if the symptoms persist. He/She will start with the specific medications. If an internal disease is found, whether it's kidney disease, iron deficiency or a thyroid problem, treating that disease often relieves the itch.Lastly,Phototherapy can also be tried.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional queries.
