Hi there ~
I am glad to know that you are athletic and have "enough strength to still fight a lion in Africa" (BTW there are lions in India too, though not too many!). Anyhow, I believe that you have had a sensation that is neuropathic in origin or a simple TIA
or a transient ischemic attack
, in either case you need to visit a doctor to find out what may be wrong, if anything is. I am sure you will be reassured to know if there is nothing wrong. I hope and wish the best for you.
Take care and have a lovely day!
