Things are hurting me

I'm in pain! Last night i couldn't get to sleep because i had pain in one spot of my back. This was very annoying as it was just one spot and nothing i did was able to get rid of the pain. When my back is sore usually i can just sleep on my stomach and it will go away rather quickly but this didn't go away. I woke up this morning still in pain. It has subside and i don't really feel anything at the moment. My now my right arm elbow is hurting me from what i don't know. I didn't bang into anything. Its not like I'm dyspraxia. I also have a general soreness over my body which i usually get from walking hard the day before. I didn't nothing of the sort like that yesterday. So I'm rather confused why I'm in pain.
