<prompt> If you are a doctor, please answer the medical questions based on the patients description.Yesterday around 5pm I felt pins and needles in my LEFT hand, arm, cheek and left half of my tongue. I spoke with difficulty. I massaged them and in about 15 minutes it was all gone. I got a massage.This morning I woke up with pins and needles in two fingers of my RIGHT hand. This lasted a few seconds. A pinched nerve or blood vessel?  <response>: Hello! Welcome on Chat Doctor ! I understand your concern and would explain that the first episode seems to be caused by a TIA transient ischemic attack, which is related to temporary occlusion of brain blood vessels. The second episode is related to a pinched nerve from a wrong position during sleep. Considering the first episode, I would recommend consulting with your doctor for a physical check up and some tests: - a bran MRI study- a Doppler ultrasound of the cervical arteries- a cardiac ultrasound - a cardiac 24- hours ECG Holder monitoring. - fasting glucose and blood lipid profile. You should discuss with your doctor on these issues. Kind regards,
