Welcome to NeuroTalk:

Is your leg pain, in the muscles? the knee? A shooting pain like down the back? (Sciatica). Only in the thigh? It would help if you can describe it carefully. Is it aggravated by walking?

I'd try first off some magnesium lotion on that leg.
It is inexpensive, and at WalMart and Walgreen's now. (new)

This can be a quick indication of what is causing your pain. Only
$5.98 for 8oz which will last a long time. Use only on intact skin, about a quarter's diameter rubbed in. You don't need alot at a time. Once or twice a day.

If you are gluten intolerant there is going to be possibly other nutrients you are not absorbing orally properly. Zinc, iron are also often low. You can get those tested when you go to the doctor.

That fever of 101 and over is high... in an adult 101 is considered serious. This suggests an infection, or possibly lupus.
Not all patients with lupus get fevers, but some do.

Lupus + young female is what they will look for first.

I think you need to keep a log/journal of each day and your symptoms, and food intake. See if something pops up as a trigger. Doctors like logs/journals as it helps they decide on what to look for. You really need to get this looked at carefully... lupus can destroy your kidneys...so get to a doctor ASAP.
