I have shoulder ouchy and tendinitis (tennis elbow) of which my doc said the tendinitis is 2ndary pain from trying to accommodate my shoulder.
He gave me a coritsone shot. Hurt like a
!! But cured it right up. I've also had coritsone shots in my shoulder, which cured it too... for about 6 months.
Actually, like Jman1 said, physical therapy, certain stretching & massage & heat & ice (and ibuprofen) can definitely make it feel better, but as for curing it.... I dunno.
