i have pain in my lower left rib cage. it started shortly after trying to lift a fallen tree from the road just over a week ago.i am taking ibuprofen and this helps during the day.the pain is reduced but stiil hurts if i apply pressure to the area.the worst time of the day is first thing in the morning when i wake up.i am assuming its some kind of muscle strain and not an internal organ problem.i am 52 years old and yes i do smoke and do like a drink...what doyou think ?? awaiting your reply stuart.
