small fiber neuropathy
"Symptoms of my Small Fiber are burning,  prickling and deep pain in extremities. Gabapentin felt like it worked for the first few days. But then needed to be upped to the next dose after about 5 days.  Then the cycle continued. some relief, then needed to be upped again.  In my case i found my body built up a tolerance too quickly. Was up to 3000mg and experience no relief at all. Its very hit or miss when it comes to small fiber neuropathy."
