I'm sure someone else can answer that about Dr. UM, but I took arnica post-surgery. I also took a few hydrocodone for pain a couple days later, but I probably could have done without them. I've also taken some ibuprofen. But as far as natural supplements, I was taking 1000 mg of bromelain (for swelling/bruising) and vitamin c because it speeds healing and reduces the chances of infection. Whether or not any or all work, I can't answer that. But I am an advocate of keeping a balance of alternative medicine and conventional medicine. Either way, I still have inflammation in day 8 which I don't think is highly unusual for a mesh procedure.
Anyway, I think Dr. UM is very familiar with homeopathy and natural alternatives based on some blogs I've read. Here is one of them... http://sportsherniablog.blogspot.com/2007/08/recovery-from-nerve-pain-due-to-ap.html
