Stray- I'm so sorry to hear that you fell and hurt yourself. Have you gine to the ER yet. Beisdes the back pain, if you hit you head you should really get in there asap especially if you taking your pain meds. Concusions dont always feel like something is wrong.
It will put your mind at ease and they may be able to do something else to ease the pain if nothing else is internally wrong. But of you can feel pain internally insread of just the bone or muscle pain then you should really get it checked(I think thats what you ment by internally/)
I hope you are feeling better
In suffering, we are given the key to a door which most rarely
get to open. Behind it lies the ultimate gift which is only visible
in our darkest hour.
