Hello, my husband is 26 and got diagnosed with a dilated blood vessel in his brain about 2 and a half years ago. This vessel apparently has a very small and slow leak, if I remember correctly. Well my husband still gets really awful headaches. They are not migraines. We ve been through the ringer trying to find out what was going on and a cure for it, with no luck! Once these headaches come on really bad there s no fixing them. We have not been able to find him any relief as of yet. Now, he s had a headache for the last 5 days or so and it varies in intensity. He just had me feel this big, hard and immovable lump ON the actual mastoid bone behind his ear. It s hard as a rock and feels like the bone. He says some of the headache pain is coming from it and he keeps getting sharp pains in the middle of his shoulder blades. I m concerned with his prior history and wondering if I should just take him back into the ER tonight to have another MRI and CT scan done? What are your suggestions here?
