66 yr male - I wake 4-5 am every am go pee then get tingles in the upper body - chest and shoulder. Then no sleep for hours. Overheating is related.?

You probably. need your prostate to be checked for the enlarged prostate. Tingling could be due to hyperventilation caused by the stress from frequent wake ups. Also do not overheat the room which prevents you to go to sleep.
Urine test. Your symptoms are probably nonspecific but it would be worthwhile to have a urinalysis and urine culture done to check for a urinary tract infection. Also check your temperature to see if you run a low grade fever. Discuss this with your Physician.
