I had a minimally Invasive TLIF L5/S1 and a joint removed. Since surgery I have had numbness on opposite hip (improving) as well as ongoing bladder retention problems. I am currently on Detrol. Thought it was getting better then had significant problem again this morning. I don't know what caused the setback. I am not sure if swelling is going down or meds just kicking in more on good days. Is this a common aftermath of surgery and is there a good chance this deficit is temporary? Anyone having had similar surgury please put in your 2 cents!
