Pain in my arm

Since I found out I was pregnant it seems to have gotten worse. Before I would get this pain every once in awhile like once every six months. Now I’m getting it about twice a week. In my sleep I get woken up by a sharp throbbing pain in my upper arm. It feels like my muscle is tearing. I can’t sleep through it and the only thing that will take it away is two extra strength Tylenol. It doesn’t completely take it away it is just manageable after that. For the rest of the day it’s sore. I’m trying to not take any medicine but I can’t handle it. I’m up for about 3 hours dealing with it. Has anyone had anything like this?
