Blood circulation problem related to weightlifting

Might be related to atherosclerosis? If so, going on a plant-based wholefoods diet for a month could solve your issue.

Edit: How old are you? Do you eat a lot of foods high in cholesterol and saturated fat? (meat, dairy, eggs, oils)

 

Have you had any history or family history of diabetes or other circulatory problems? Other symptoms?

 

I had the same problem. What fixed it for me was to stop using my arm as headrest and make sure my arms were bent as little as possible when falling asleep. Hope it helps.

 

Diabetes type 2 can be reversed within 10 days or less with a Whole-Foods Plant-Based diet, as proven in clinical trials. Check out the work of Drs. John McDougall, Joel Fuhrman, Michael Klaper, Michael Greger, or anyone on the Physician's Committee for Responsible Medicine really.

I'm quite convinced that this would help with your cardiovascular issue too. My dad's cholesterol dropped 40 points and his hypertension vanished within 3 months of doing this ~90%. Also great for athletic performance.
Watching the documentary Forks Over Knives might be a great starting point if this is something that interests you.

 

I have the same problem if I sleep on my back with my arms folded... my forearms go numb. Don’t worry about it just change you position.
