I've never used vaseline to get rid of a blister ! All I do is use a pin to prick it then, using light pressure and a tissue, soak up the fluid that comes out. I leave it 'open to the air' - to let it dry out, then remove the 'scab' after a few days once it's toughened. The skin underneath always fades to normal.
Use an anti-fungal ointment (as used to treat athlete's foot) and Vaseline. Also, change your underpants daily.
Oragel or some type of Vaseline works best.
Neosporin
Vaseline salt water mix
Put salt on a spoon and keep it on the blister for 30 sec and repeat 3 times
To prevent foot blisters, wear properly fitting shoes, moisture-wicking socks, and use lubricants or powders. If a blister forms, clean the area, apply a blister pad or moleskin, and avoid popping it. Foot blister tape can help reduce friction and protect the skin.
A blister has clear fluid under the skin, and a blood blister has blood under the skin. If it's a burn, it's most likely a blister.
Coolidge
A wart or blister.
To treat a blister on the arch of the foot, it is best to clean the area with mild soap and water, apply a blister pad or moleskin to protect it, and avoid popping the blister to prevent infection. Keep the area clean and dry, and wear comfortable shoes to reduce friction. If the blister is painful or shows signs of infection, seek medical attention.
You probably won't be able to completely get rid of a blister caused by a temporary crown. You could call your dentist and see if they had any recommendation. You could use Orajel to help with the pain.
