Don't know if I should be concerned or not, my stomach has been a little gross feeling, and I have a sharp pain that comes and goes on my right side more towards the back in the middle... it come and goes... (note its not directly on the back side of my body.. the side.)
Hi,  looks like you are suffering from cholecystitis. Pl. get one ultrasound abdomen done and consult a medical or surgical gastro enterologist.
