Help, I doupt it's fibromyalgia but what is it?

Hello,
I found this site in my search for information about my symptoms.

For two months I have had sore muscles. I feel pain and aching when I move or stretch after sitting and lieng. Otherwise I feel OK just sore (like a workout hangover) for the past three weeks I have noticed swelling in my arms and legs. My legs feel heavy and tight. The doctor did some blood tests which I haven't heard back about. He talked about fibromyalgia but I have no sore points or many of the other symptoms. My pain is uncomfortable but it doesn't seem as bad as fybromyalgia pain is didcribed. Any idea of what this could be? I initially thought this was a drug reaction to Zantac but I stopped that a month ago and symptoms are getting worse. I am going to try no MSG Aspertame or caffine and see if that helps.
