I hurt my elbow playing tennis. Is that an urgent care visit?
It can be. Pain on the outside of the elbow after repeated swings is often an overuse strain that improves with rest. Come in if the elbow swelled quickly, you heard a pop, you cannot straighten it, or a fall caused the pain. Our clinicians can examine it and decide whether an X-ray is needed.
Can you treat a skin tear on an older adult?
Yes. Skin thins with age and tears more easily, especially in people who take blood thinners or steroid medicines. Rinse it gently, cover it loosely and come in if the flap is large, bleeding will not stop with steady pressure, or the area turns red and warm. Our clinicians can clean and dress the wound.
