For the past month I have been experiencing a tightness in my left neck and shoulder, as well as tingling a little in my left arm, and occasionally numbness behind my shoulder the creeps up the neck behind my ear. It's not really that painful, but more of a bothersome and distracting sensation. The weird thing is that it is not that consistent. It will be fairly subdued for a few days and then may flare up again, especially if I stay up late drinking alcohol. I was thinking that perhaps it was a herniated disc, but I read online that it could also be anxiety.
Personally, I think it cannot only be anxiety because even when I am not stressed out, I can feel some of the numbness and tightness and when I tend to dwell on my symptoms, only then do I begin to feel anxious. Now that is has been about a month with these symptoms, should I consider going to see a doctor? To reiterate, really experience no muscle weakness or any serious symptoms, other than the distracting numbness and tingling and the rare tightening sensation in my neck/shoulder. Sometimes that tightness can be felt in my upper chest, right below my collar bone.
I would love to read some of your comments/advice.
