Husband has been taking Warfarin since 2007 due to a congenital heart defect that has resulted in 3 heart surgeries. He is 51 years old and has a pacemaker and a porcelain valve as well. The top portion of his heart does not communicate electrically with the bottom thus the reason for the pacemaker.
He has suffered with what is now a 24/7 headache since around that time and it occasionally represents itself as a migraine. Is there anything that can be done to help alleviate his suffering?
