Good morning.. just lately as in the past 2 weeks I have been getting pain on my left side only when I move or breath.. it comes and goes.. have tried taking I b profen and it seems to help sometimes but not all the time.. and the pain is only on my left side.. esp when I try to stretch or move or breath sometimes. Like right now there is no pain at all but this morning there was like a stabing pain for about a hour then went away.. it might be just a weight issue since I'm over weight but then like I said it only started about two weeks ago and I remember that I had this last year about the same time when the weather changed from warm to cold.. just wondered if you could give me any ideas of what it might be.. I am 55 yo and 5 7" and weight about 300.. thank you for your time
