I hate Being in pain

My left knee is hurting after my dog pulled me across the yard to get to the fence to see the neighbors dog theres three holes in our back yard and as my dog was pulling me he pulled me into one of the holes tripping me which hurt my right ankle before I could get my foot out of the hole he pulled which made me fall I fell onto my knees and hands both of my wrists are still a little bit sore but my left knee is still hurting quite bad plus I already have problems with that knee because when I turned 16 I tore something in that knee which caused it to lock up so it normally hurts and bothers me every now and then but never like it is right now its hurting quite bad after that
