Hi. I woke up last week and the outside skin between my right thumb and forefinger had become slightly numb. I noticed also that the upper part of my right arm also had a similar sensation. However I often wake up with pins and needles in my hand / arms as if I have pinched a blood vessel or vein in my sleep. The numbness is slowly diminishing after a week. Is this something I should take seriously? I am 53 years old and otherwise healthy. My BMI is below average, by blood pressure is 130 / 80, my heart rate is ~80 / minute and my blood sugar is 4 on a scale of 2 ~ 6. I also walk 1 to 2 hours a day, 7 days a week and generally feel fine. I don t think I have any high risk factors but I wonder about other potential degenerative diseases such as Alzheimers as I find that my short term memory sometimes turns off lately. Again, any suggestions are welcome.
Namaste Welcome to Chat Doctor Greetings of the day There seems nothing wrong with you.  Pins and needles is due to nerve compression, also Vitamin deficiency especially B12 will aggravate the symptoms.  Start taking Multi vitamin supplements which will definitely help you.  As You have a good lifestyle like walking for 1 - 2 hours which is perfect indeed.  Try meditation and yoga which will help your memory.  If problem persists get a routine assessment done from your physician. Take care Regards
