I think that you should request a blood test for Lyme disease. What you describe could be a symptom of lyme, as well as a number of other conditions including compressed spinal nerves, low back injury and more seriously MS. I have a cervical spine injury and I get tingling and numbness in my hands. I also get tingling and numb feeling in 3 of my toes.
The only way to get an accurate diagnosis is to get tested, see what the doc has to say
FYI - both my son and I had Lyme and neither of us had the bulls eye rash that is so common with the disease
