Rest periods

How often do people take breaks with manual methods on average? I was tugging last night and have been basically at any time I can in the day in 5-10 minute sessions.

Unfortunately I woke up the next morning with numbness that is only really starting to recede at the time of writing. Should I just hold off until the numbness recedes completely? And how often can you get away with breaks without totally screwing up your pace?

Not even sure how it happened to be honest, there was no burning or pain that I noticed and I know I wasn’t applying more tension than I usually do.

Naturally of course I’ve been panicking most of the day. What should I do?
