Hi, I am 33 year old with a history of chronic back pain, sacral nerve damage, asthma, allergies (mainly as a child), migraines and anxiety. Everytime I get a headache it is on the left side of my nose and the vein there swells up and pulsating. It is a throbbing pain and pressure and is consistent with my pulse. Excedrine migraine is the only thing that gives me some relief. The headaches are completely random. Any advice you can give me as to what this is, I would greatly appreciate it.
