Hello,I was diagnosed with a colloid cyst almost 16 yrs ago,since then,I have gone deaf in my left ear,almost blind in my left eye,and a myriad of disturbing symptoms over the last 10 yrs.I have had a "bad"headache for almost 6 weeks,My P C does not seem to think it is urgent,so I have to wait for a referral for my M R I.I dont know if I have hydrocephalus,I went through all these other afflictions and ordeals with the doctors always diagnosing me w/something else never considering the cyst.I am scared that it has grown,should I just go to the E R or should I wait the week or more for the M R I and then a consult??
