Can the 6 day steroid medpak help chronic headaches? And if so, how often can tbey be used?

Careful. While the Methylprednisolone 6 day pak is used widely in medicine, i wouldn't consider it as a first choice for treatment of a headache. Your family md understands well all the risks of using these meds. I would not use them without his guidance. See him before taking anything! steroids are not benign medicines and their affect on your adrenal glands can be problematic.
