Hello I'm 30 years old and about 260 and about a week ago I started having sharp pains on my right side that comes and goes. Sometimes it's burning sensation under my right ribs and other times it's a sharp pain in the right side of my stomach. I've went to the emergency room and they did a blood test and urine test but don't really know what the problem could be. Everything came back normal. I just need some help in finding out what to do because I'm worried it's my appendix even with the blood test being normal. I would be very Greatful for any help. Thank you for your time.
