<human>: I had an appendectomy two weeks ago. I have intermitent sharp pains on my lower right side that feel like a knife. It topples me over and lasts for about 30 minutes. Urinating seems to have helped previously as it takes pressure from my bladder off the area. I have nausea and Im vomitting up clear spit like mucus. I am salivating a lot.  I have severe bloating and I am burping a lot. I have a stomache ache and a head ache. I have taken my temperature and its normal at 97.1. I went back to the hospital a couple days ago and they ran blood tests and did an ultrasound but found nothing and sent me home. I tried to go to work today but went home at lunch because I was disoriented and nauseas. I am again very bloated. I am afraid if I go back to the hospital they will just send me home again. What should I do?
<bot>: Causes of severe pain in abdomen after appendectomy can be due to ::Abscess formationIntestinal obstruction symptoms are suggestive of a complication of appendectomy and ultrasonography is never sufficient in such cases. Please get the CT scan done, insist on admission till you get alright. If the CT scan findings are suggestive of a complication, you may also require Laparoscopic or open approach second-look procedure (re-operation). This is sometimes life-saving.
