I have a hard day with my side. Lots of numbness, my right leg feeling heavy, my right hand spazzing into a tight little ball. This usually lasts 24 hours or so. Then my balance will come back, my hand will relax, and within an hour I'll get a splitting headache. (Not as bad as when my brain exploded, but worse than a "nagging headache," which I get several times a week now and they don't really interfere with my life.) Anyway, this bad headache comes and plagues me for about 2-3 days. It's not a constant terribleness, but probably a total of 9 hours out of my 15 awake hours, I'm in enough pain for it to interfere with my life.
I'm about half way through the blazing headache part of this cycle right now. And before you ask, I'm drinking water and hot tea and diffusing peppermint oil. Already took one nap (woke up in more pain than I went to sleep in). Dark and quiet. Soft music. Nothing has made it better or worse (except the nap), although holding perfectly still does seem to help a little.
