I am in the middle of a miserable migraine

. I have chronic sinusitis as well. The two of these together seem to ramp up pcs symptoms, such as nausea, to a very unmanageable level.
Was wondering if anyone has dealt with this terrible trio of issues, and if so, how do you cope? I literally have to stop and go to bed for a few days until things improve, but that is tough to make happen. My fatigue level goes through the roof as well....
Many thanks for your input!
