Had two little episodes today where I couldn't really speak, all that was coming out of my mouth was garbled words. Never happened to me before, except maybe as the result of a messy evening.
First one was about 3-5 mins, then a few hours later the next one took me about 20 mins to gradually return to normal.
No drink or drugs today. No real pressure or stress (actually been taking it easy for a bit after what I thought may be stomach / kidney but turned out to be musculoskeletal).
Only unusual thing I can think I was doing unusual when the first one happened was soldering with some roisin flux, but the window was wide open and I've soldered loads of times before.
Is it worth going hospital or docs, or just hope it doesn't happen again.
