I was diagnosed with IC and endometriosis a few years ago. And a few months ago I started getting pretty severe pain in my leg, finger, and arm joints. It seems to be all over. I’ve also been getting rashes, ones been on my arm for 3 months now. I’ve gotten them on my face and forearm. I’m so tired all the time and now I’m having terrible headaches. I’ve been to the Dr and tested for arthritis and R.arthritis, both are negative.I had lymes last year and assumed it was that, but that was a dead end too. Has anyone ever had these symptoms or know what they could be. I feel like I’m playing yet another round of find the hidden condition, and I’m too tired from the round I played just 2 years ago!
