I Have Been Experiencing Tingling Sensations In My Legs And

I have been experiencing tingling sensations in my legs and arms for over a month and am losing weight. I have significant pain in my neck with limited mobility. I have had a brain MRI and MRA, a neck MRA, an EKG, bloodwork done-all results are normal. I had an EMG on my left arms and legs and have been diagnosed with carpel tunnel. I am still however, having the tingling sensations and am now on gabapentin. I am struggling here as I do not feel well but do not know what else there could be to look at. I do suffer from anxiety and have been on paxil for years but I do not feel that anxiety is the issue. If I am having anxiety it is because I do not feel well and no one can provide answers.
