Unfortunately there is not much treatment for a broken pinky toe. The doctor or nurse will just "buddy-tape" your toe, tell you to wear flat shoes, maybe prescribe some pain medications or suggest OTC medications, and send you on your merry but limping way.
Buddy-taping is just using tape to bind the broken toe to its unbroken neighbor. This stabilizes and aligns the repairing bones in the broken toe.
Over the counter anti-inflammatories (NSAIDs) are fantastic for these situation. They provide pain relief but also minimize swelling. Best NSAIDs for this is ibuprofen (Motrin, Advil) or naproxen (Aleve). That being said, check with your doctor or pharmacist before adding or mixing any medications. Fell better!
All of what you've read about docs doing nothing is exactly what I heard. However, I've broken my pinkie toe twice and the second time something either didn't heal right or I fractured it lower or SOMETHING, but it has never been right since. This was easily 8 years ago. I don't limp or anything but if my foot is in the path of my running little girl, I always pull it out of the way. If you have insurance, I say go to a doc just to be sure! Good luck!
Broke my little toe, didn't need a doctor to say so, but after 11 days of walking (I'm a mail carrier) the pain increased every day..X-ray said broken and the toe was not fusing back together..Now wearing a special shoe and have to have another x-ray in 2 weeks..If it is not fusing back together Doc said surgery!
