headaches and horners syndrome

Hello all, my horners syndrome is getting worse lately and my eye is seeming to be a lot more closed, it is hard somedays to have any light or be outside if it is really nice out. if you do not know what horners is here is the definition is the combination of drooping of the eyelid (ptosis) and constriction of the pupil (miosis), sometimes accompanied by decreased sweating of the face on the same side; redness of the conjunctiva of the eye is often also present. It indicates a problem with the sympathetic nervous system, a part of the autonomic nervous system. Medical imaging and response to particular eye drops may be required to identify the location of the problem and the underlying cause.^{[1]
My biggest problem with this is it also causes unbarable headaches and I can barely function somedays due to the pain and they can not treat Horner's Syndrome appropriately until they find the underlying cause, so for now I take different pills trying to stop the headaches and subside my pain, basically meaning that I just have to live with this, not a lot of fun or anything that I care to live with ever.
Yesterday the headaches and pain were so bad that on Sunday night I did not get to sleep until around 5am and then was awake by 7:30am, so I managed to get a whole 2 and 1/2 hours sleep. yuck. I phoned my doctor and he managed to get me in right away to see him. Thank god, so we rode our bikes downtown and Matt came with me to the doctor. To say the least the headaches are just getting worse and so is my eye. I need the doctors to find out the cause soon, this is becoming a hassle for living my daily life and is also affecting Matt as when I am sick and have headaches, he is so concerned and tries so hard to help me deal with the pain.
I am still on my tylenol 3 for the headaches and also another pill and now on oxycodene as well for the pain, at least on that last night I got some sleep. Felt so good to get my 7 hours of sleep. 
So there you go, hopefully they will find the cause soon and be able to treat that and then with any luck the headaches will stop. Have a great day.}
