I had a bone marrow done when I was a newborn. The doctor said that I would always hurt when it rain. I was never over any medicine. I done research at a support group and they said it was supposed to stop hurting within a week. Everyone sad it never stop hurting. The doctor have medicine but do not recommend the medication because it can be addicted. Any one suffer from this? Sometimes I can used a copper bracelet and there are days that I can't tell it working until I take it off. The pain is so bad I want to scream.
