I have the same problem. I’m told it’s my heart. I’ve gone through every heart test possible. No it’s not my heart. Then your told its old arthritis. The problem is they actually don’t know themselves. I use a heating pad to relieve some of the pain. I still say it’s some form of inflammatory and the big three is not the right meds to fight it. We need and anti inflammatory medication. I’m working on that now. I see my infectious disease doctor Monday. I also see my Neurologist on Monday I’m going to ask him. He does a lot of scientific research maybe he might know something. You have a good day. Gloria
