Did I injure my arm from working out?

Yes.

@rangerr, thanks for solving all my problems, you’re a godsend ;)

I’m always more sore two days after a workout than I am the day of or the day after. My trainer has told me numerous times that this is normal.

If it feels like muscle soreness from working out, it’ll probably get better soon. Ibuprofen might help, as will stretching. A nice hot shower also helps me feel better. If you’re going to continue the workouts, you might want to make sure the pain isn’t from an injury that you can make worse. When my muscles are really sore and I work out again, they usually feel better afterwards. If you have an injury, however, you could just make it worse.

Make sure to warm up before you work out and stretch after. Take it easy, and don’t push yourself quite to that point. Is there a coach or trainer you can talk to? Finally, if you don’t feel better in the next day or so, you might want to see a doctor.

@Parrappa I answered the question. [:

@MissAusten, I used to be sore a few days after working out as well, but this doesn’t feel like that, that’s why I’m so worried.

You really shouldn’t have worked out so hard after a year and a half long break. You pushed your body too far, now take your lumps like a man.

In any case, soreness rarely lasts as long as a week. If the pain hasn’t reduced at least somewhat after 7 days, you may have injured yourself. I injured my right pectoral muscle last year and it took a good 4–6 months before I was completely pain-free.
