Consultation advised. The abnormalities are likely not all related to your headaches. Unfortunately this Q & A box isn't designed for diagnosing illness. You would be best served with an INBOX TEXT CONSULTATION at Health Tap. You would need to upload results of any tests, if available, as well as your medical history. You would NEED TO MAKE YOURSELF AVAILABLE for 24 hours to reply to any questions from the physician.
