I have just started seeing a nuerologist for my migraines , after many sugestions from my regular doctor. I just had a mri down as well as i think they call it a BRE and VRE, its were they test my brain waives, one was were i layed there for 30 min with sensors all over my head the other also had sensors but i had to listen two so clicking sounds through headphones then i had to watch this video. Anyways, my migraines normally cause nausea and stiffness and numbing in my head and neck , i was washing my hair tonight and relized i have a big lump bigger than a quarter on the left bottom side of the head. It is soar to the touch and makes me feel the same way as my migraines, it also sticks out where you can see it when i put my hair in a ponytail, I am worried, i have an appointment next wednesday. And the nurses said the doctor usually doesnt look at your test results till right before then, should i be concerned and call him tommorow. Any ideas what this lump could be?
