I am in extreme pain and have been for 3 days. This started in August. I have had CT scans, endoscopies, colonoscopies, ultrasounds, etc. Nothing has been found. I have been put on a very strong antibiotic which seemed to help for a while, but pain returns. I have been taking a pain killer and a high dose of motrin the past few days, and it is not touching the pain. The only other thing I can think of at this point is the mesh sling that was put in a little over a year ago. I am in so much pain, but when I go to the hospital nothing is found so I am reluctant to go back to ER for a 5th time. Help please!
