My hand and arm gets tired when I write.

I have the same. Some days I think my arms don’t even work they are so weak. My pain started in right side and now it’s both, but predominantly right side. I equate that with the fact I am right handed and right side dominate.

Yes I’m experiencing the very thing on my right side. Shoulder to foot. Forarms has little bumps underneath them and tender to touch. I have them on my left but only hurt when I touch. Right side hurts all day non stop. My legs also feel bump and have tender spots around shins, calf, near ankles. My joints are popping, and muscles are twitching.

Yes I have them all over my body. I was wondering was I the only one have these painful knots under my skin. They really hurt to touch. I keep heating pad on my legs and arms. What do you do for the pain

Exacly like you, right side pain and weakness then it started on left side too
