I've been going to the gym for about a year. The last 3 months I decided to make my training routine a bit more, upper- back/ traps/ shoulder intensive. I basically am doing full body 3 times a week. On every training day after worm up I started with overhead pressing. The problem is that about 2 weeks ago i got injured. Started feeling pain from my neck area going trough my left shoulder. When I run my fingers trough my upper part of my spine I am feeling pain. My question is firstly is this due to bad form in your opinion or just the overloading I've been doing to my upper back. Second should I try and wait out the pain to disappear on its own or should I go see a doctor?
Thanks in advance!
