Big pain, new pain

I feel like absolute crap right now.  I am dazed and my mind in a fog.  I have so much 'regular' pain from all these  conditions and the 'regular' is too much.  Now, a new pain.  Left buttock to outside of left thigh severe pain and causing extra 'new' pain down leg, front, sides and back.  I already have Fibro pain, neuralgia and sciatica pain and arthritis pain in that leg.  It is all wound up together all at once.  Moderate to severe pain from shoulders to fingertips, entire back and right leg.  Now this other thing.  I want to scream.  I am near tears.  OH and the other new thing, my calves and feet are always swollen which means more pain too.  6 weeks with the edema and about 2 weeks I think with the butt/thigh big pain going on.   Sherry
