I'm sorry you're feeling punky today! It's VERY hot and humid here right now, temperatures in the upper 80's. I went out for just a short drive to a nearby restaurant to pick up some food, and it about did me in.
I was driving at age 15 myself. Back in the "old days" (I'm 60") a person could get a driver's license at 15 if he/she completed a driver's ed course and was the "sole driver in the family". My father had died when I was very little so my older brother was "sole driver" (he was 15 when my father died) til he went off to college. We relied on cabs and friends for a couple of years, then *I* turned 15 and became the "sole driver". I had to be real responsible real early, as I was driving around my mother and my 8 year old brother. Maybe that's why I've had only one accident in all these years of driving -- when a car starting up from a traffic light stopped suddenly in front of me, and I didn't react as fast...and only one "moving violation" -- a bit of a "lead foot" going through a small town. Maybe your daughter will take it very seriously too, knowing she has to be the driver for her ailing mom!
I hope you are feeling way better today! Vertigo is no fun at all, and unfortunately seems to be hard for docs to treat. Did the antivert give you some relief? If you are still having those horrible spasms (hopefully not!) you might check with your neuro to see if your meds can be adjusted. For example, valium is sometimes used to treat both muscle spasms and also vertigo. I have found ativan (same benzodiazepine family as valium) to be somewhat helpful for my muscle spasms, and there are a few people on this board who use klonopin for spasms/spasticity issues. I haven’t a clue how this class of meds would interact with the other stuff you are taking…I just wanted to say that there are other things to try, so please do check in with your neuro if you need to.
I also find stretching the spasming muscle(s) in the opposite direction from the tightening helps to loosen things up, which then helps with pain (does that make sense?). Brisk, light massage of the affected area also seems to help relax the muscles for me.
Here is some general info on controlling muscle spasms:
Hang in there
