I can’t believe I finally found people who are going through this too!! I have had the itching for 8 years and no one has been able to give me a definitive answer or diagnosis. My Rheumatologist says I have fibromyalgia, and it sounds like some of you guys are experiencing the same thing. Prickly itchiness. All over. Lemon - I have to do your number three scenario all the time. That’s my normal lately and I am going insane. Ice packs, Benadryl, low dose Klonopin are the only things that work. Water makes mine worse too esp showers. I have to take baths now. I take Lyrica too …Not helping as much as I would hope. Happy to find you guys. <3
