pull your ear lobe gently... if it's painful it means you have water in your ear.. (swimmer's ear)
to get rid of it you can try the following..
1) Bend your head and body forward, so that you are standing and you are facing your knees 2) Come up until your head is now facing the floor and turn you head to just one side, so that your ear is facing the floor. Pump your upper body a couple times up and down. You may have to repeat this 2-3 times to get the water out.
If that doesn't work.. try one of these three things.
1) mix 50-50 white vinegar and distilled water.
2) 50-50 mix of water and isopropyl rubbing alcohol
3) peroxide (read instructions on bottle)
For 1 & 2 Pour less than half capful into ear. Shake head, tilt head so ear is towards floor and let the water pour out holding a tissue underneath.
I don't think u need to do ^this if u use alcohol, as it should dry the water out. But check with pharmacist just in case.
