I was diagnosed with autonomic dysfunction, small fiber neuropathy, complex regional pain syndrome and mild POTS in January; I was told possibly some genetics involved but I also believe a series of necessary pelvic surgeries caused severe nerve damage. I have had pain, numbness and tingling, burning sensations, and a multitude of other symptoms for years. I have been to a variety of doctors in every specialty there is. I've tried all sorts of medications, including Lyrica and Neurontin. It wasn?t until I found an ANS specialist this January and was finally properly diagnosed that I had been finding some relief from some of the symptoms. My ANS (neurologist) has me taking Topamax (50 mg twice a day). He had tried to go higher with the dose but I had memory and concentration problems at higher doses. The current dose of Topamax (I've been on it since March) is helping with my neuropathy symptoms. I take Atenalol for tachycardia, Ultram for pain, and a few other medications for allergies and asthma. I also take some vitamins and nutritional supplements. It is amazing what a proper diagnosis and the right medications can do. Not all medications work the same for individuals - it can be trial and error to find out what works for you - talk to your doctor and see what options are available to you. I hope you find relief too.
