When I am standing, I get a large pain under my lower left rib. It feels much better when i sit down, it goes away. At first i thought this might be just a stitch but when I laugh or cough i can feel it pop. If i put my hand on it. I can feel it pop. What could this be? It has been bothering me for over a year now, and it disrupts me as i cannot stand for long periods of time. What could this be? Thanks.
Without an examination, it is difficult to say what is going on.
It is possible that you have injured the fascial bands and/or ligaments which hold the lower ribs in place. But, you also have to look at the structures which are under the ribs; the spleen, diaphram, large bowel, etc.
If the problem continues to bother you significantly, you will need to have it checked out.
I feel similar pain when standing for longer than 10 minutes. Especially when I feel appetite. But, in my case, one of left ribs is enlarged. This seem happened after completion of my TB (pleural effusion) treatment. I was prescribed with AKT-4 for almost 10 months.
