Ann, I am so sorry you have been suffering so. I understand your aches and pains because I have a type of arthritic disease that also flares as you describe. It took a long time and the proper medication to get it somewhat under control.
Your description of how your illness started and the symptoms that ensued sound like reactive arthritis. There is excellent information about reactive arthritis here: Spondylitis Association of America. At their home page, go to about Spondylitis and read the information about reactive arthritis. There are multiple pages. One will list the medications that are used to treat it.
I don't understand why you have had to see so many different rheumatologists. Did the first two have differing opinions and you are trying to "break the tie"?
Cold weather really impacts my arthritis and my joints. I started wearing long inderwear in September - LOL.
