[|Human|] About a month ago the tip of my tongue started tingling at random intervals, maybe once or twice a day.  This past week it has been tingling 8 or 10 times per day, lasting about 30 seconds each time.  Today my tongue started tingling, and now my left fingertip is tingling.  Should I be concerned about this?  I have diabetes and I take metformin and insulin.
[|AI|]  Thanks for your query, I have gone through your query. The tingling sensation in the fingertip and tongue can be because of the diabetic neuropathy or secondary to any nerve injury. Nothing to be panic, consult an oral physician and get it evaluated. Meanwhile you can take nerve regenerating Chat Doctor.  You have to keep the blood sugar level under control. Once the blood sugar level comes to normal, the tingling sensation gradually reduces. I hope my answer will help you, take care.
