strained muscle issues can take a LONG time to heal.. I had a repetitive muscle strain injury to my arm, and it took a YEAR before it stopped bothering me on a regular basis.. and 5 years later, I pushed it too hard again chopping firewood, and flared the old injury back up. So now I have to take it easy with my right arm again, knowing it'll take a long time before it's fully healed again.

Ya just have to give it a few months, but if you push yourself too hard again, you'll just redo the damage.
 

Way too many people take way too many things way too seriously.
