For the past couple years, off and on, I've noticed a sensation that can last for days at a time, and the feeling is like someone is pulling on my hair (taut) on my scalp in the vicinity behind my left ear. Sometimes, it can happen on the right side, too. But most of it occurs on the left side. Initially, I thought it was from certain heavy styling products on my hair or who knows what, but now I don't think that's the case.
I am having this now for almost a week straight. I'm currently under a lot of stress because I've been having chronic pain that is also off and on, in my left shoulder/arm area. This pain has been going on for 4 months now, and the Dr. and chiropractor seem to think it's from my job, a Repetitive Stress Injury. Part of me wants to believe that but another part of me is fearful of it being something serious. So I have gone to my Dr. repeatedly for CBC's and got a shoulder xray, chest xray and diagnostic mammogram. Everyone keeps telling me not to fear cancer, but when someone has pain that has come out of the blue, it makes the mind wander.
What could be causing all this? I'm scared but so far tests are normal. I have 2 enlarged lymph nodes that I think I've had for a long time and the Dr. said they are not that big and that they are most likely leftover from a long ago viral infection and they never went back to normal size. Because of all this pain and weird feeling behind my ears, I'm scared to death that this is all related and it's something serious.
Help me figure this out. Please give me some advice.
TIA
