I was in the ER more than 2 months ago and was given a shot of morphine and a shot of an anti depressant both in the same arm. Shortly after my arm went numb in the spot where the shots were given and there's also a tender spot that hurts to touch next to the numb spot. I was thinking it would eventually go away. I've been rubbing it and trying compresses and no change. It's now been over two months and I don't know what to do it is really bothering me.
