In late summer I started out for a run. I had not run in a while but do a lot of weightlifting which kept me in shape. I have always been a sporatic runner and when I run I go for about 3 miles. When I went for this run I had to stop after only two minutes because I was having sever pain under my right lower rib cage. Ever since this I have not been able to run and even with walking I get this sharp pain occasionally. The pain comes and goes randomly. It hurts sometimes when standing and sitting. Sometimes it hurts after I eat sometimes it does not. It is so hard to figure out what this is. I am going to my doctor to have it looked at next week. I think I am going to ask for an ultrasound. Can anyone relate to this?
