Hi. I have slight autonomic dysfunction. Symptoms include pacs, tingling and twitching all over, especially my head, which causes dizziness. My newest symptom is numbness on my entire left side. Very little pain, but some. This has been going on for two yrs. I have had an extensive work up including EMGs and even a small fiber biopsy. The only test that suggested anything was a failed tilt table test. No medication has worked (pindolol, lyrica, cymbalta, gabapentin, tegratol, metoprolol, verapamil). Now what?
