Tendonitis is irritation or inflammation of a tendon, the tough cord that connects muscle to bone. It usually builds up from repetitive motion or overuse rather than a single injury, and it tends to settle into the same spots: the shoulder, elbow, wrist, knee, and the Achilles tendon at the heel. The pain is often worse with activity and with the specific motion that caused it. OS1 treats tendonitis on a walk-in basis, the same day, with no appointment and no referral needed.
Tendonitis is typically caused by:
Tendonitis can feel like other problems, so getting the diagnosis right matters. An OS1 physician examines the area and, when it is useful, uses on-site imaging in the same visit. Digital X-ray can rule out a fracture or arthritis, and an open MRI can show the tendon itself if the picture is not clear or the problem has been going on a long time. Knowing exactly which tendon is irritated, and ruling out what it is not, is what makes the treatment plan work.
Most tendonitis improves without surgery. Your OS1 provider builds a plan that may include modifying the activity that is aggravating the tendon, a brace or support to rest it, anti-inflammatory care, and a cortisone injection when the inflammation is significant or slow to settle. For some patients, a PRP (platelet-rich plasma) injection is an option to support healing in a stubborn tendon. Your provider explains which approach fits your case and follows up on your progress. If the tendon problem turns out to need surgery, OS1 refers you to the right specialist.
