I get pins n nedls easily in my arms (ulnar nerve) sometimes tingling down leg, teeth n face. No pain. Just on and off p's and n's. Have gastro probs?

P's and N's ? Have you had recent dental treatment, the sensation you have sounds like galvanic current. This electromotive force can exist in the mouth.
Neurologist. Sounds to be like you should go see a neurologist (nerve doctor) as well as a dentist to really find out whats going on. Your pins and needles don't sound normal. Symptoms of the teeth may be unrelated to your arms and legs and stomach.
