Hi Lyris!
First I'd like to say that you are doing the right thing by seeking out another doctor. I would be doing the exact same thing if my doctor was dismissing concerns that were so great to me!
If you are keeping a headache and Migraine diary - I would track how the lump feels when you get a Migraine or headache - that way you have documentation for your new doctor. The lump may be caused by numberous things and should be take seriously by a doctor if it is bothersome and changing. If you would like to start using a Migraine an headache diary - Teri Robert has made three different types that are downloadable HERE. A diary can be very beneficial when speaking with your doctor.
Are you taking any preventive medication at this time? Anyone who has more than three Migraines a month needs to be taking something for prevention. You can find a list of Migraine preventives HERE. There's growing evidence that Migraine is a progressive brain disease. A recent study showed that Migraines can cause brain damage, and that people with three or more Migraines a month are more susceptible to this damage. For more information, see Is Migraine a Progressive Brain Disease? and Yes, Migraines Can Cause Brain Damage.
I know you're going through a rough time. If you'd like some additional support, come join our discussion forum. You'll need to register again once there because it's a separate membership database, but you can use the same member name, email address, and password that you used here. You can find our forum at http://forums.healthcentral.com/discussion/migraine/forums.
I hope to see you over at the forum! Please stop by and let us know how you are doing and what the new doctor said!
Good Luck!
