Did i strain my muscle?

[Blair the character...???]

Today, i was aching, my arms,back,and hands and legs. Then when i went outside i ran a little like in the store,skipping and stuff but nothing major. Now, my right foot pain moderately severe. It hurts when i move it and if i stand on it to long it hurts. I heard a little popping sound once and i feel it popping. What should i do? What happened, tips and or anything of that sort? Now the thigh is starting to hurt a little,well the half of my leg, the lower half.
I don't know if this helps, but my hand is hurting now also well my arm is.
Now my whole leg is hurting and my foot is sweating.
