That is an excellent question and one that may be best answered by your primary care doctor
or a doctor specializing in the care of toes and feet such as an orthopedic surgeon
. Based upon the history you have provided, there are a few possible causes for the symptoms you are having but since it is difficult to diagnose you over the internet, you should see a doctor as soon as possible to have this evaluated and treated appropriately. Based upon the story you have provided, there is a potential that this could be a broken toe or perhaps a badly bruised toe that is giving you these symptoms. Your doctor may choose to take an x-ray
to evaluate what is happening with your toe and if there is an issue, depending on what they find they may want to splint your toe or perform other treatment options. While you wait to be seen, you may consider some symptomatic treatment of this toe pain with ice and NSAIDs to help with the pain ,and also trying to keep pressure off of your toe to decrease the pain that you are feeling. It is important to see your doctor though to find out what this is and how to best treat it.
