Hello, I Understand That It Is Best To See My

Hello, I understand that it is best to see my doctor as with most Heath issues test are needed as well as an exam. However at the time being I don't have transportation. And I just want to make sure that the issue that I am having is or is not something that I need to find a quick ride to my doctor. In advance I thank you for all insight on my problem and advice you can give me. Well I do have a few herniated discs in my back and kneck, not sure if that has any connection. But the problem is this morning the side and top of my foot is swelled up, I have never had this happen before. I did not fall or twist it. Again any insight or answers you can provide me with is greatly appreciated, thank you
