And the blister

Vac extender. Dime sized blister nearly half inch raised. Pain to touch obviously. Anything other than stopping extending to accelerate healing? Already determined extending with it is not a helpful option between this and really disgusting chapping I've fought with for months.

Stop training, apply heat with a wet wash cloth 3-4 times a day for 5 minutes at a time. It will soon break and empty naturally. DO NOT pop it, this will cause scaring and will most likely prolong the healing cycle. Once in naturally drains you can start training again.
