So stupid me almost lost my finger last night at work, it got caught in a chain on some machinery and went around a gear. The hand surgeon said it was a near amputation, only held on by 1 tendon. He reattached the remaining tendons, muscle, 2 arteries, and one vein as well as putting in a plate and screws to hold the bone together. The Dr. said I should stay away from cigarettes and caffeine as they can restrict blood flow to the finger. Do you think that marijuana would act similarly? I really don't want to chance losing my finger if the arteries don't grow back, but I could definitely use the mj for my pain... For now I'll hold off I guess.
