What if i put a lot of pressure on an unbroken ankle, will it cause long term damage?

Possibly: For people with acute hives (i.e., a single episode lasting just a few days), it may not make a difference. For those with chronic hives (present for >6 weeks), many can experience worsening of the hives, more frequent outbreaks, etc., with consumption of alcohol. Some may not notice any change at all. See an allergist or dermatologist with experience treating hives for more details.

Ankle Sprain: Ankle sprains are very common injuries. There's a good chance that while playing as a child or stepping on an uneven surface as an adult you sprained your ankle--some 25,000 people do it every day.​
