try asking about herpangina. its a virus that makes swallowing extremely painful. visible symptoms include canker sores or ulcers anywhere in the oral cavity, including gums, tongue, cheek lining, throat, etc. the virus can be contracted by several things(mostly feces because of the bacteria and actual virus), however i contracted it from a pool that was not properly chlorinated. i lived on popcicles for a week until they finally gave me Tylenol with codine.
