I second Sherrine. We can't tell you if it's fibro or not, but many of us who have been diagnosed with fibromyalgia have a lot of trouble with the same issues. I have to buy super soft sheets too. I wear my socks and underwear inside out to get the seams away from my skin. I can only wear elastic waistbands, and finding a new bra is torture. I've been looking for a few years and still can't find any new ones I can stand. Don't get me started on shoes.
It's very typical for people with fibro to have sensitivities to touch and pressure. Nope, you aren't crazy.
