I have round strong magnets. Would you suggest using one or two? I could tape one or two on my wrist, on opposite sides, I imagine. They are very strong.

Thanks for the information about keeping wounds covered. The surgeon said it would heal faster covered, but if I kept it open to air, would scab, and be less painful. He didnt think the amount of time it would add to the healing would matter much, if I could get the pain down. But really, I can't keep it open to air; I need to cover the thing with a good layer of padding and foam to protect it from bumps.
