headache

Hi,

I'm very new to this, but need some help.  After spending 7 hours in an urgent care clinic for an extreme headache, I was told the only finding was CT showed a fluid filled ventricular cyst.  The headache has been around for about 3 weeks and is getting progressively worse, with visual changes in left eye (where headache seems to be concentrated).

I sometimes get so tired I cannot keep my eyes open... at this point I am often very cold also.  After a short nap, I usually warm up and can function for a short while.

I was prescribed Vicodin which dulls the pain but does not eradicate it.  Does anyone have any advice?  I have made appointments with a Neurologist and Opthamologist, but the earliest I can be seen is 2 and 3 weeks from now.
