Bruising

Good morning, I came into the clinic last Wednesday for my steroid injection in both wrists my left wrist feels mostly back to normal however my right one has quite a deep bruise and I'm finding writing/typing very difficult with sometimes sharp pains going in my hand/up my arm? Not sure if it's because I'm right handed therefore it's taking longer to heal? But it's quite painful/worrying as haven't had this type of reaction before to an injection. Note: I did have a bruise on both wrists but the one on the left has gone but the one on my right wrist had remained.
