Had appendix removed 7 weeks ago and recovered nicely at first. I now feel some pain (discomfort) to the left of the scar (not severe, rather annoying for most part). Is this still healing scar tissue? When I lie on my back, head elevated on a pillow, pain moves up the right side to the left of my shoulder blade, at times across the whole shoulder to the left side as well. It is a sharp pain and more intensive when breathing heavy. Hospital did a lung x-ray (side view right side) after mentioning it during follow-up visit, but found nothing. My own remedy is try to lie flat on my back and relax consciously, which sometimes helps. Returned to strength training after 6 1/2 weeks thinking it might help as I did intensive training prior to surgery.
