I had back surgery on Sept 8 2016. After the surgery I had headache on the 4th of October I had pain and pressure in the head that doesn t go away nothing gives relief. I presently still have pain and pressure in my head. I noticed lying down helps and caffeine. I d gone to the Emergency three times this month with other symptoms disoriented, slurring, feeling weakness, nausea and or vomiting. My blood work came back abnormal outside of dehydration. Also in the night my bp was dropping to low and at one point I was woken up and another bp cuff was put on to check my bp. I was given a enternist in emerg she wanted to addmit me and I asked if I could deal with this on outpatient. I had a CT scan the results were normal. ( I wanted to deal with what was going on on outpatient being I was scheduled for a move outside of the area I was living ) I also was diagnosed with glaucoma prior to the back surgery I had eye surgery. The pain and pressure in my head and today I have bruise like rings on whites of my eyes. I at this point don t know what it is I should be doing. I definitely feel frustrated and having to function is a struggle.
