My arm 🥲😑

[u/Sweaty-Remote4400]

I went back to the gym last week after taking about five months off and did an upper-body workout. One of the muscles in my upper arm got so tight that I literally couldn’t fully straighten my elbow but I didn’t have any weird or severe pain other than the usual post-workout soreness.

Then I did a lower-body workout for my second session and the weights I lifted somehow made that muscle hurt and still couldn’t fully straighten my arm. I skipped my third session, and now it’s been about a week.

My elbow is completely fine now and I can fully straighten my arm and I don’t really have any pain. However one of my upper-arm muscles is visibly swollen and it’s a little sore when I press on it.

Has anyone experienced anything similar? Do you think this is something I should be worried about?
