Hi Jennifer, welcome!! Can't help you with the Lovelox, never heard of it. I had an epidural for my TKR on 9th Jan 08. It went well, they give a sedative too. I drifted in and out of the surgery, never felt a thing. Heard a bit of hammering at one point. Apparently I kept asking the surgeon lots of questions as he operated, he apologized to me after that he couldn't always respond as he was a little busy and couldn't always hear the questions!!! They also gave me a leg block and after a surgey I had hardly any pain for a day or two, I was also on a pain IV thingy, you administer it yourself. Then on the third day, I felt my knee!! Yeooooooooooowwwww!! That's when you start on the real pain meds!!!
Josephine will be along to give you lots of help with medical questions, she's on UK time, so puts in different hours.
Anyway, you must be glad to be getting your knees done now eh? It will be a long haul for recovery but worth it in the end. Just keep hanging out here, there are some really fun people on this forum, a few really nutty ones too eh Pattii...just kidding!!!
