Whoa, this is terrible. I am really sorry to hear of your pain! I have been a long time migraine sufferer and I get the full blown nausea and vomiting, need a dark room, absolute silence. Basically I need to go to sleep when it happens. Mine though are triggered and I know the triggers now. So, I avoid that. Believe it or not, stress can ramp me up to being prone to the migraine though so I often feel one brewing. So, what can they do for the cyst? So, is your cyst fluid filled? Is there a treatment plan for the cyst? Could it be aspirated? I've just now tried to read what I could about it. It doesn't seem all that common.
What is actually causing the headaches, do they know? The pressure it is putting on the surrounding area?
