Is Prolotherapy A Fake Is Prolotherapy Expensive?

Is prolotherapy expensive? - is prolotherapy a fake

I recently received a shoulder injury that was almost 2 weeks, and it does not seem better. There is a point where I feel no pain, at least on my arm all the way in line with my body, ie, | or if "or" out of my head "|" my arm, c is the thing I think that if it hurts a little. But it is for about three days after the injury, so do not think that there is more healing. I have heard of prolotherapy for complete muscle strains that no longer belongs to heal, but I wonder if it was expensive.
