I was also very cranky, irritable, and "down" on Friday ... a "black" day. Dark thoughts, emotional.
Low blood pressure & trouble standing. My head would swim.
Low blood sugar.
It was not good.
I did wonder why my Dr was quite emphatic about 3 days and only 3 days. Now I'm glad she was that emphatic!!
-----------------------------
Incidentally, I have headaches just about all the time. Drs tend to ignore me when I say that or just tell me that I need to reduce stress.
Things that may help:
My eyes seem to change quite frequently, so I've got to keep on top of my glasses prescription.
I also use eye drops on dry days.
My sleep was quite bad for a while, so I've created a cocoon of silence which helps with that.
Exercise is supposed to help, and sometimes it does.
I've reduced the amount of caffeine I use because caffeine doesn't make pain go away at all ... makes it worse.
Dehydration makes the headache worse, so I drink quite a bit of water.
Sinus problems are part of my headaches and after 5 years on a waiting list, I will finally see a specialist in December!!
I've been diagnosed with TMJ ... evidently I grind my teeth, and it shows with my dental issues. I should start using a mouth guard at night.
And I've been diagnosed with reasonably large brain cyst, but apparently it's not causing me any problems ... I've been told.
All that and I can say that prednisone did absolutely nothing for my headache!! It was actually a bit worse.
