I tested positive for Calcium Channel AB (10x above normal). I have had constant bilateral leg pain since May 2011. I have POTS. I have fatigue. I have dry mouth. Havent had an EMG. Based upon my antibodies, my doctor thinks I have LEMS. I am going for IVIG treatment this week. The pain in both my feet, calves, hamstring and butt are my worst symptom. I take medications for the POTS which stabalizes my dizziness. I would like to make contact with more people who have LEMS to discuss diagnosis and treatment.
