I'm going to try and pick up more too Momma C. and something a little extra.
Stringy, I forgot that I was going to mention a few other things that seemed to work a bit for me and my headaches... specifically the sinus headaches, but other types of headaches too. I had forgotten about it, and will have to put on my list to pick some up myself. Peppermint oil. I wish I could remember the brand the one was that I just loved and worked so well, it's on the tip of my tongue, but I can't spit it out... lol. Mine came in a little bottle, about the size of a lip gloss tube, and it had a roller ball on top. I would put it on the sides of my nose, and on the pressure points on my head and neck. It really did work! I bet you can find something similar in a health store. Just the peppermint oil would probably work just as well. I also used to use lavender oil, and willow bark, and put them in steam and put a towel over my head, and breathe them in. It's worth a try if the horseradish doesn't do the trick for you!
