Blister
 

I've a blister on the underside of my finger caused by repeatedly squeezing the trigger of a cartridge sealant gun whilst doing household decors & repairs.

The blister is unconfortable , so for the time being I'm refraining from doing more of the same work involving squeezing with my fingers.

Question is: should I puncture the blister as to let the fluid out ? ,
theres no sign or reason for any infection at the moment.

Try to keep the blister whole as the fluid is acting as a cushion to prevent further damage to the finger. The fluid there will be reabsorbed in time and having the blister intact is the best way of preventing infection. If the blister does pop by itself ensure that the wound is clean and dress with a non adherent dressing.

Okay will do, thanks Hayley.
