First of all I have to ask.........what is it you want to call your Doctor ? lol. I have called mine a few names that I cannot post here
Could your arm pain be related to your back problem or is it something brand new ? I believe that if you feel it is possibly something serious you should bite the bullet and call your physician.
If it is a sx you have with your anxiety, then refocus and do whatever you practice to take your mind off the pain and anxiety that may go together.
The holidays are coming up and many are going to find the anxiety rising right along with the anxiety the physical sx will also become more evident.
I hope you find relief from the pain and keep posting, we are here for you.
I understand your frustration with this pain. I have irritable bowel syndrome and sometimes the pain is just unbearable and I start thinking oh my god I cannot live with this anymore. Problem is that makes the pain worse because I start to panic. Panic = worse pain. Well sod!!!!!
It's not fair is it and I'm sorry you are having such a rough time. It could well be the anxiety making it worse or it could be a real problem. Don't let a doctor make you feel stupid. Ever. If you think it's serious and want tests then go for it. Nothing is more importantthan peace of mind (and sound health).
In the mean time try and breathe through the pain (I know, I know, easier said than done!!) but anxiety will not help the problem. Try some relaxation on your shoulder areas, lavender oil, gentle massage maybe and heat packs...I hope you are feeling better soon, remeber, you're not alone in this
