Ugh, that sounds painful hiimkelsi! I agree that the best thing to do would probably be check with a specialist  to see if there's an underlying condition causing your symptoms. It sounds like it could be more complicated than just your run-of-the-mill muscle fatigue.

In the mean time, you might try taking a ginger bath to relieve the discomfort. My yoga teacher clued me into this heavenly remedy for body aches and soreness, and I've been amazed at how well it works. After a particularly vigorous asana practice one evening, she told me to go home and prepare a very warm bath with ginger root. She said any form of ginger will work; you can throw in a couple of tablespoons of ginger powder or paste, add a few drops of essential ginger oil, or (her favorite) put some fresh ginger root in a sock and run the hot water over it.

I tend to be a bit skeptical of any sort of medicinal technique, albeit traditional or alternative. But good old fashioned ginger root put me in my place. It's like a panacea. I've found it decreases swelling and inflammation, calms me when I'm anxious, and even helps if I have a tummy ache. If you have any in the house, you might give it a go until you can get to a doctor.

Is there any chance you could have sickle cell anemia?  A friend of mine does and she always has pain like that in her arms and legs.  I really hope it isn't a clot because those are super scary and dangerous!  You should definitely see someone ASAP.
