Hi Doctors, So here's my problem. I had an open appendectomy exactly 2 months and 8 days ago. I had it on January 25, 2016.7 weeks after, I sudden ran in the stairs, forgetting about my surgery. But there was no effect or such. And then after 5 days, March 25 (2nd month after surgery), we had a family swimming so of course I had fun on the beach but I did not run nor did intense swimming. But after 3 days I guess, I always feel this pain in my left hypogastrium, beside my upper groin. I also feel pain in my back, and my sides. Then this day, april 2, I suddenly feel this pain right under my incision. The pain comes and goes. It's bearable but I get nervous about it. I have thoughts that the scar inside might have opened, and I don't want that to happen. I'm not experiencing any infections and my scar is perfectly fine. I don't have fever, nausea, and I'm not vomiting. I have cough and feels like I'm out of breath sometimes but it's surely because of cough. I'm just worried about the pain I always feel. Please let me know what this is. Thanks!
