[|Human|] Two years ago I had an ablation for atrial fibrillation. The operation was successful but I was left with a lump in my left(lower)abdomen that caused extremely painful attacks that lasted between 1 and 2 hrs. and continued for a year and a half about every 10 days. That petered out eventually and I no longer have painful attacks but still have the lump that sometimes becomes sensitive. I was prescribed hyoscyamine for the pain but never took them. I m still having bowel problems.
