Hammer toe looks to be potentially painful.

Kevin 1951 Chevy 3100 work truckFollow this saga in Project JournalPhotos 1929 Ford pickup restored from the ground up. | 1929 Ford Special Coupe (First car) Busting rust since the mid-60's If you're smart enough to take it apart, you darn well better be smart enough to put it back together. | | | | | Joined: Mar 2010 Posts: 10,270 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,270 | The military bases require a CAC (Common Access Card) to enter the gates. My anal retentive pedantic retired Marine/Navy friend always tries to correct me when I say, CAC card. I immediately redress him and insist that I actually said CA card (which sounds the same). Squid (he was in the Navy at the end of his career) then gave me the stink eye. My grandpa had a hammer toe on the piggy which stayed home. He had Doc Evans just chop it off. Shortly after that, it quit hurting after it started feeling better... Back to the topic, tomato/potato. We all know what it is. Carl

These doctors like to "conserve" - yeah, right  | | |
