I feel like i strained a trap and some neck muscles on my left posterior upper back and neck. I don't know how to identify if its a strain, or a pull. I don't know if i should train through it or stop training.
I dont' know if its left from my last dead lift session or if i slept on it wrong.
I think it was a sleep related train. Temperature dropped, heat didn't turn on and i was exposed to temps as low as 35 and i think that could cause muscle problems.
