Hands & Feet Going Numb/Constant Pain

Hello, I have fiber neuropothy pain & nerve damage with numbness in both hands & feet. My neurologist can't seem to find out whats going on. My hair very dry has been coming out like crazy with thinning eyebrows. I have been getting very forgetful,foggy memory. Nails on hands & feet get blue/purple at times. No libido at all! Bad heavy periods. Gained weight. Severe constipation.  I'm in pain all the time. Eyes twitch,facial swelling,terrible dizzy sick headaches. I get numbness & tingling in my lips & face.Ears ring & hearing seems to be getting bad. I woke up the other night choking like I had something in my throat & for the last few weeks I feel like some thing is choking me & putting lots of pressure on my throat.
I'm sorry to keep going on but there are so many more symptoms. I forget what I'm talking about all the time & can't focus!
I'm afraid that one morning I'm going to wake up & won't be able to walk because I have no feeling left in my feet. I have sever pain & doc has me on Nurotin/Gabapentin 2700 mg a day. The doc said all blood work came back ok. That was 5 months ago & things are getting worse losing more feeling in feet & hands. I had a nerve test done & they did find nerve damage. I'm not diabetic either. Whats going on with me??
Please help, I feel like I'm alone on this & loosing the battle!!

Hello and hope you are doing well.

The nerve damage could be causing the pain. Check to rule out thyroid disorders, it can cause the symptoms described by you. This can be detected by a simple blood test.
