[Skin Concern] My skin on my back is itching horribly when it gets wet when I shower or when I sweat. I'm not sure what's going on. Does anyone else struggle with this or have any advice?

Beauty Tips For Body Care
About two months ago, I noticed that my skin on my back was starting to itch every time I showered. I usually take hot showers so I lowered the temperature and switched soaps. I also thought it might be an allergy to something coming into contact with my skin, so I've slowly ruled out my detergent, lotions, soaps, hair products, etc. The weird thing I have no rash, no bumps, nothing. It just intensely itches!It's starting to slowly get worse. It's starting to affect my legs and starting to itch when I'm not sweating or showering now. I've tried taking antihistamines and using calamine lotion but those only gave me very temporary help. Right now, I'm using coconut oil on my skin to see if that helps. I've stopped using soap on the areas that itch.I have a thyroid issue and had that checked this week but turns out that's fine. This is just affecting my everyday life. I can't work out, I can barely shower or do anything that causes my skin to get wet.Any advice is appreciated. I've never had this issue before. I usually have dry skin but I've religiously put lotion on my skin since I was a kid (I'm almost 30 now). Please help me 😭
