question: three weeks ago I had a bad headache, blurred vision and some numbness on l side of face.  I went to the ER and they did a CT and bloodwork.  I was told all was ok and they sent me home with ERY 333 in case there was an underlying infection of some sort.  They did mention a small amount of fluid on L eardrum.  I went ahead and followed up with an eye dr and dentist.  The eye doctor did the exam and dialated my eyes.  He was concerned about Giant cell arteritis and wanted the results of my bloodwork.  I had to go back and have that particular blood test drawn.  The number was a 10 and not 50 or more so he ruled that out.  I then went to my dentist and the xrays showed a possible abcessed root.  Second to last molar on the L side.  Because it was such a big filling he went ahead and pulled it.  I was then tols to continue my antibiotics and he prescribed more.  I still have a on again off again headache, never any fever.  Tooth area feels beter today is two weeks, although looks like it is still draining a bit.  I was out and about today and my husband said that my was was all red.  I looked in the mirror and it was all red and bloodshot looking.  Then after about an hour it was normal again.  I am starting to get a bit stressed wondering what is going on. I finished my last antibiotic tab today also.
