I hope this is a good place to post a question like this... if not, please let me know.

I went running on Monday for the first time in a long while. The run was for 4 miles. At the end of the run, my foot felt really sore around the area of the lateral plantar fascia. Not sure if that is really what is strained, but that is the area of where the pain is. That afternoon my foot felt more sore and to this day continues to be sore.

I have been putting that area on an ice pack which does relieve some of the pain/tenderness. If I stand on it, it becomes sore quickly. I just want to know if I have anything obvious to worry about or if it just sounds like I over did it and just need to continue icing it and keeping off it as much as possible. Any help is appreciated.
