Recently, I've noticed chronic (3+ months) muscle pain in my quads and biceps, as in, they are tender to the touch. I feel (and the pulmonologist agrees, he's very knowledgeable), that it may be polymyositis. My rheumatologist checked my CPK levels and they were elevated, but not much (150).
She's sending me additional lab orders to see where the protein is leaching from, but if I'm already on immunosuppressant therapies, will I be able to get a proper diagnosis? I'm willing to advocate for myself, but I need to know what further testing I'd need...nerve conduction, biopsy?
