Hello again! I recently. Have been dx'd with small fiber neuropathy by skin punch biospy on foot and ankle. I really appreciate the responses that I have received and begs me to ask my doctor more questions at our next appointment. One suggestion raised was Dorsal Root Ganglion involvement and after doing a lot of reading on the subject it seems to Be a logical step to take. However, being as I've been struggling for 15 years With his and have finally found a dr. Who at least bothered to test me, how do I go about broaching he subject without alienating him. It appears in the past whenever I question a. Dr. It becomes a very touchy subject and in then end told to live With It. I do not want to alienate this dr.as I feel he may be he last one I see that can provide answers.I also wonder why he only tested 2 sites instead of the required 3 that would have told the SFN is not only in my foot. Also as I have exCeSsivee sweating, frequent UTi's, IBS, difficulty. Urinating, a Qsart test would clarify. Autonomic involement, but yet again I am fearful of saying anything. If. Anyone out there can think of a diplomatic way for. Me to handle this I would be eternally grateful!! Also the. Dr has put me on Methotrexate. Has anyone else tried this and how did it help?thAnk you again for your responses!! Thank God I found this site!!
