Dear Sir/Madam I have gone through your query and read your symptoms. In my opinion, the symptoms you describe are suggestive of nerve involvement, and mainly peripheral neuritis, or compression neuritis can cause such symptoms, now since you say you are not diabetic, lets concentrate on other causes, and the next major reason for peripheral neuritis is Chronic Alcoholism and long term use of certain drugs. so make sure if you fall in one of those categories. also make sure that you do not have any spinal problem or pain, as nerve compression can also give such symptoms, moreover local compression can also cause such symptoms. you need to consult a neurologist, and work with him to find the cause. I hope that answers your query. If you want any more clarification, contact me back.
