Maybe wrong category but it fits the best.

Hey everyone, I started working out more recently and thus looking in the mirror more often. I rather quickly realized that for some reason my left pectoral is slightly bigger than my right one, and that my neck goes a bit more to the right in its natural state. One of my friends with whom I work out also mentioned to me that my pull-ups tend to be imbalanced which I’m trying to work on.

To get to the actual question: can a muscle imbalance like mine result to a “tilted” neck and thus would be solved by fixing the imbalance, or should I get worried and go see a doctor in case my spine is fucked somehow? I’d love to hear from anyone with similar experiences to mine!

Thanks and have a nice day !
