What is a good minor injury/sickness that would stop you from going swimming?

Uhhh... your period? o u o

Hmm....I'm going with Fever.

Having a cold, flu, fever, or some type of arm or leg injury (like a sprain).
I don't think period would count because I've gone swimming on my period and actually when in the water your period stops. However, if you have severe period cramps you probably wouldn't want to swim.

Paralysis.

Legs chopped off.

Death.

Dysentery.

Dog ate my health.
