Have had feeling of buzzing or motor running in pulses in lowest abdomen/bottom area. Coupled with heaviness in legs, extreme jaw/gum pain, involuntary muscle twitching, a swollen gland on right side of throat, and fatigue. Symptoms come amd go in intensity, sometimes vanishing for days. Neurologist guesses virus in nervous system. I am 63...was in otherwise good health before this began two months ago. Any ideas who to see for diagnosis?
