It is very difficult to tell what has caused the change in intensity of your headaches. I would suggest you to consult your physician about it because Coumadin can also cause headaches which are usually sudden and can indicate internal hemorrhage.
If these are migraines you need dose adjustment of your migraine medication. I would also suggest you to do some relaxation exercises like breathing exercises and meditation and try natural supplements like magnesium and Migravent.
Take care!
