Hello everyone... my MRI shows 8 cysts in the sacrum. I am scheduled for surgery with Dr. Feigenbaum in Dallas on December 20. I was wondering if any of you every noticed that your symptoms before surgery sort of came and went? I am currently feeling pretty good which makes me wonder if I am doing the right thing in undergoing this surgery. Other times I hurt so much I can't even do grocery shopping... symptoms come and go and are different each time they come. Thanks for your wisdom!
