Hi, i feel as though I strained a muscle in my chest approximately 8mos ago or so and it has healed in a timely manner each time. This time I did the same injury I believe but now it it very sore and has caused me pain in my left arm and hand is numb. Left side. I frequently lift weights ( each body part once a week) Before this injury I had just worked out my chest. It feels like part of my chest plate area. The very sore area is just below my clavicle bone/ I am a 52 otherwise healthy female. I do have Crohn's disease which is VERY manageable. Can I take Motrin? I only take Tylenol, due to the Crohn's disease.
