About 4 weeks ago I was in the gym and decided to use a specific sit up machine that you lay on flat and after doing like 5 or 6 to show someone how to do it, I resumed my regular work out and a couple day’s later I woke up stiff and stretched and heard a kind of pop, like the sound when you crack your knuckles from my chest and later that day I started to feel a tightness in that area. After getting the nerve to see a doctor they said that they are sure thats what I did and that it would take a couple weeks to heal, to do warm compresses and take Ib profin.
Well the 2 weeks went buy with no discomfort, so I resumed regular activites, work involved with some heavy lifting. A couple day’s ago the pain and discomfort returned. Could I have re injured it? Thanks
