Suppose you have an air lock..What to do??
First Thing don`t take any medicine neither any balm. Just do any kind of movement that would put a direct impact on the affected part then ask someone to do acupressure on that pat or acupuncture would be best if you can bear  the pain.Then to prevent re-airlock on that part put hot waterbag on that part as it would make the air near you lighter and there would be very less air near your body which would prevent any more chance of air lock in that part again...

Hi, Sorry, I have NO IDEA what an "Air Lock" other than in a submarine, spaceship or decontamination area is. Thanks, Neil
