Excellent advice. I will only add (for the benefit of others), next time just call 911 or at least call a friend or family member for a ride to the emergency room instead of driving yourself.
I had a situation last year , fortunately non-emergency, and I will add it here in case others experience similar symptoms. It started with what I would call a muscle spasm in my left leg that lasted about a minute, followed by persistent numbness in the left foot. This happened right after doing some major re-landscaping that probably strained my back a little so I assumed it was related. I mentioned it to my doctor at my next visit a few week later and his initial thought was a pinched nerve caused by over-doing it. I continued to have spasms about once a month and when I told the doctor at my annual physical, he referred me to a neurologist to figure out what was going on. Long story short, they did not find any nerve related issues so next step was a brain MRI which revealed a benign brain tumor (meningioma) . The tumor was pressing on the part of the brain responsible for right side motor function but had not invaded into it. Come to find out that the spasms were actually small seizures. Anyway, the tumor was removed 2 weeks ago without any complications and I am now released to resume or at least ramp up to normal activity and driving (I guess I should give up MMA ;-).
The moral of my story is: do not wait 6 months to check out what seems like a minor inconvenience. In my case it was a benign tumor that is unlikely to reoccur but it could have been something more serious and instead I could be going through something where waiting could have cause it to be much worse to deal with, both for me and my family. Even if you are as stubborn as I am, don't put your family through that.
