I am so sorry that you are having such a hard time. I agree with the rest...I think you need to see a doctor and find out what the oxygen is for? You said you've been on it for a year, so I imagine you have other medical problems too.
As for the leg throbbing and swelling. With Fibro you will get the pain, but usually no swelling. My feet and ankles hurt and swell alot, but I think that is from one of my medications.
I hope you are able to get things straightened out and start feeling better. I'm sorry for the way some of the hospital personal have made you feel. I've gotten that in the past and just try to ignore it. It really makes me so mad. If you get someone who is really cruel and not hospitable to you, then I would ask for someone else. That will show up on this person's next work evaluation!
Good luck and please keep us posted. I hang out on the Fibro thread. Please call your doctor or get a knew one if you think you need someone more familiar with your diagnosis. Look forward to hearing from you. Hang in there!
Never regret something that made you smile!
