I had Bariatric sleeve surgery 1 year 5 months ago, yesterday I lift a very heavy box with circular saws , drill and alot of other stuff..as I lift the box I felt I strained the area of to the left of my sternum..I had to lay down..now I been very uncomfortable, something is going on at that area, and I feel discomfort on my back like about on the T4- T5 to a side, like my pain goes to the back more then in the front area
