Over the past few weeks following a personal issue which temporarily spiraled me into a sort of breakdown, I've been getting tingling sensations in my hands, feet, and further afield. This has been for the last 2 weeks.
Tonight I got a sharp pin-like pain in the tip of my left big toe, for about 5 seconds. I am also getting a similar pin like pain on the back of my right leg. So from tingles, now into pains.
What are the possible causes, and what kind of examination should I seek to start eliminating possibilities?
