Suggest Medication For Pain And Soreness In Left Foot

I am am 14 year old girl. This morning I woke up with a very sore left foot, so much so I couldn't walk on it.. I believe the pain is derived from my second toe and runs down my foot. Although I can move the toe with my finger, it is very very painful to move it with my muscle.. It feels almost like a very dull ache, possibly a sharp pain when weight is put on it. It also could be described as feeling like it has: "gone to sleep"?, as though there is a lack of blood?????????? Please help me because I cannot walk like this and I am very worried! Thank you so much!
