both hands? could be stress, cervical spine injury or even carpul tunnel. If you have a computer job I would consider it the latter.
Stroke or TIA related would only be to one side, extremely rare for it to impact both sides. Then it is not really tingling it is more like loss of feeling or motor control or ability to move the body part. If it was stroke related it would impact limbs (arm & legs) on the same side.
Tingling lips or loss of feeling to the lips can be a sign of TIA/stroke. It feels more like when your hand/arm goes asleep.
Trust me, if you are having a TIA/stroke you usually know it, it feels very uneasy, you want to talk and tell someone what is happening (if they are there) but nothing comes out of your mouth, you can only make motions, maybe point.
TIA and strokes are different, impossible to communicate during a stroke, if you get hit with a more severe stroke it feels more like an electrical shock you cannot get away from, you may even hear those brain cells and tissue being destroyed, sort of sounds like an egg frying in a pan, and afterward, pretty hard to unfry one.
I would try some aspirin for a few days taking only 1 per day.
someday science will catch up to what I'm saying...
