Anuerysm, nerve damage, or something else? Need opinions...

Hello! First off, allow me to thank you for taking time out of your life to address my concerns. I have been very scared these past couple of days, and am in dire need of other people's knowledge on this topic, in order to achieve piece of mind. I feel my situation is very complicated, so I'm going to start off by telling you my history. I've had two surgeries in my life; both were for tooth extractions. I've had two concussions; one left undiagnosed from a fall I took when I was younger, and the other in 2006. I received this concussion as a result of blacking out while standing up, then falling dead-weight onto the concrete below, hitting the LEFT side of my face. I blacked out as the result of taking a bad batch of psilocybin (sp?) mushrooms. I dabbled in other recreational drug use from 06-07. I'm not proud of this, I only list these because I feel it will help you understand my situation. I've taken mushrooms on three separate occasions (including the black out incident), mescaline one time, and LSD four

...away until I was injected with a painkiller. I received a CAT scan, but was told that nothing abnormal was found. I was sent home shortly after with the diagnosis of a tension or migraine headache. The next day went by without an incident. However, the 2nd day after I was attempting to cough up some mucous when the same throbbing pain from a few days ago took over the back left side of my head. Since then, I've noticed slight discomfort in the base of my throat. My head hurt for the next few hours; but the pain lessened as time went on. Yesterday, my head hurt again, but it was not nearly as debilitating as it had been before. In fact, it didn't hurt very bad at all. But I did notice that my heart rate increased, and the pain seemed to be in correlation with my heartbeats. I have a very slight ringing in my ears, and some jaw discomfort as well. I'm afraid of it being an anuerysm or stroke. Does anyone have any knowledge on the subject, and does it sound like one of those ailments to you? Thanks for help.

(continued)... LSD four or five times. I still smoke marijuana regularly, but have quit experimenting with any other drug. I do NOT smoke cigarettes and only drink alcohol on occasion. Finally, I am in a band, and I used to "headbang" on stage. For those unfamiliar, headbanging is when you bob your head heavily in rhythm to the music. Now, for the past few years (since before the drugs) I have experienced a sensation in the back left side of my head where a shooting pain runs up the back of my skull. This used to only happen when I would turn my head too quickly or something, leading me to believe I had pinched a nerve. Again, this had been going on randomnly for the past few years. Last Saturday, however, was a slightly different story. I had just ejaculated, and out of nowhere a horrible pain took over the back left side of my head. It was worse than any past experience. My girlfriend took me to the ER, as I was afraid I was having an aneurysm. The head pain lessened as time when on, but didn't go away...
