I m a healthy 66yo male. After a workout (routine bike ride(r)/40+ years) and shower, I suddenly broke out in a clammy profuse sweat, also was hungry so I ate a late lunch and felt better, but now have a sudden pins & needles type tingling and numbness in my hands, especially the right...but is starting to subside as i write this. This is unusual for me but other than these sudden symptoms, I feel okay? Any comments?
