myasthenia gravis
"Thymus tumor caused Myasthenia Gravis. Tumor was removed (thymectomy) but still have severe muscle problems, treated with pyridostigmine 60mgx5 and 5 mg prednisone x2. Which gives me about a 1-2 hour window of better muscle control per dosage. Often times causes severe cramping in neck, head, face, hands, legs.., I take magnesium to relax the muscle cramping. Also have less control of bowels and urinary. Not sure if meds help or hinder in that area. Food has less taste too."
