Hi dear Jinky ~ If you are able to handle the pain with Aleve or other over the counter medications, then do so. DO NOT TAKE SOMEONE ELSE'S PRESCRIPTION MEDICATION. You should NOT be taking your friend's Ativan. That is a prescription drug -- if you want some of that, talk to your doctor and see what he says.
Since you seem to be able to handle the pain ok with a little help, I wouldn't have the surgery either. At the present time, it doesn't look like it's a surgical event from the looks of the MRI. However if the pain changes and become worse, you should see your doctor immediately.
So don't go for surgery at this time if the doctor doesn't think it's urgent -- and I doubt he does. You have the option to say NO.
I think you'll be okay. God bless and take care, Jinky. Hugs, Lee
