Hi I've been dealing with a severe numbness in my entire heel for about two weeks now. Prior to that I start feeling a vibrating sensation in my feet like the floor was shaking. It would come and go and I didnt think much of it it has since progressed to my whole body. It will last anywhere from a couple minutes to an hour or more. It feels as if my body is shaking on the inside with no visual signs of shaking. I was labeled as pre-diabetic other than I had trouble with alcohol for years. My doctor is leaning towards alcohol induced neuropathy but has no explanation for the internal tremors. In my research I see things like Parkinson's and MS and I fear that multiple sclerosis is the cause and my doctor has been hesitant in going forward with any tests. More or less tells me to stay off Google and webmd. I'm 31 the heel numbness seeming came out of no where but then again years of alcohol abuse would explain it but not the internal tremors. Does anyone have any insight on internal tremors and other things that may cause them or should I seek a second opinion from another doctor and try and push for more testing.
