I am a long time migraine patient. I have one now that seems different. I have had it for a few weeks. I also have nausea, weight loss, sinus pressure, and overall lethargy. I am already on an antibiotic for a sinus infection. Should I been seen, or wait till the antibiotic is over? I am on day 5. I also had a sphenoid ganglion block a week ago, but have not gotten relief. Also, do I go to an ENT, or neurologist? My doctor just retired, so I am between practices.
