Costochondritis is considered to be harmless. I disagree. It can be entirely too painful, and pain can wear a person down to where they feel they are not even really alive...as well as turn a perfectly nice person into a bitch from hell.
Costochondritis also hard to spell. Frankly, costochondritis sucks. It truly does. I swear on a stack of Bibles that it is TOTAL SUXOR.
You heard it here first!
