I was seen at the hospital for 4 days for unk numbness on my left side. What brought me to the ER was the inability to speek which passed quickly. All tests were neg incl mri, ct, eeg, ekg, carotid us and echo. All labs are neg incl spinal tap. I am now having high acidic levels in my mouth and numbness/burning on my tongue and sometimes lips. The numbness has progressed to my left pinky ring finger and thumb, spots on left calf and foot, also pinky and ring finger on rt hand and big toe rt foot. Mood swings and fatigue are crazy and don't seem to be brought on by anything particular. I had surgery to repair my rt shoulder on June 10 and the symptoms started about 3 weeks following. Any ideas or info would be greatly appreciated, my pcp and neurologist have run out of ideas. Thanks
