Good to hear things went relatively ok GG, I hope it won't take too long for you to start feeling better. I'm hearing you about the hospital thing, I don't like them either, it's like one of the most unnatural surroundings there is (but ofcourse very good to have around at times).
I'm sorry to hear there wasn't a clear cause found for the pain you're going through, I hope you'll have more luck in the future
Good recovery!
