@jamiemetcalf , hey there! That’s a great idea. I checked out that condition and while I’ve never been diagnosed with it, it’s possible. Most of my soreness under the skin on my limbs (except not the ITBS) has resolved since I started taking daily Hydroxichloroquine in the spring of this year. It doesn’t help with actual muscle strain, but other unexplained aches, pains and soreness under the skin has gone. It’s amazing. It supposedly treats inflammation.
