Physiotherapy for jammed fingure

Hey! I am a basketball player and I frequently suffer from shoulder pain. I have developed swelling in my right-hand shoulder. My trainer said that I am having shoulder tendinitis. He also said that a mild tendinitis will heal on its own. So I kept it untreated. Yesterday, I jammed my finger when I tried to intercept a pass. My finger isn't fractured but it has swelled up and is really painful. I often consult my regular GP for recurring shoulder pain. I visited his clinic today too. But he suggested undergoing Physiotherapy treatment from a clinic in Toronto. I am planning to undergo the treatment tomorrow. Is there anyone here who had undergone a Physiotherapy treatment for a jammed finger? How was your experience? Can anyone share the details of this procedure? How long will it take to recover from this procedure? Please share your insights. Any advice is highly appreciated!
