Corticosteroid(CS) + Lido or Corticosteroid(CS) Alone

The clinical trial is a randomized control trial to compare the efficacy of a combined lidocaine and corticosteroid (CS) injection versus a corticosteroid injection (CS) alone on pain, range of motion, and patient reported outcomes for the treatment of common upper extremity tendinopathies and nerve entrapments that are often treated with a combination of these injectates.

A tendon is a type of tissue that connects your muscles to your bones. These tissues help control actions such as running, jumping, grasping, and lifting. Without tendons it would be difficult to control the movement of your body. A protective layer known as synovium covers tendons. This sheath produces fluid, which keeps the tendon lubricated and moving properly. Inflammation or swelling of the sheath is known as tendon sheath inflammation or tenosynovitis. This condition is often treated with an injection into or around the sheath. This injection often consists of a corticosteroid with or without lidocaine. Corticosteroid(CS) are drugs that decrease inflammation and are given for a number of orthopaedic conditions to decrease symptoms of the underlying disease. Lidocaine is also a drug that blocks the pain response, although it only blocks it momentarily. The study aims to determine if corticosteroid injection alone is as effective as corticosteroid combined with lidocaine for the relief of tenosynovitis of the upper extremity.

The study plans to enroll 1000 pts with tendinopathies of upper extremities and nerve entrapments and will be followed up in clinic 2 weeks and 6 weeks after the injection. During the clinic visits the Visual Analog Scale for pain (VAS-pain), range of motion (ROM), strength, and patient reported outcome data will be collected and any complications will be noted. Patients will also utilize a pain journal to track VAS-pain over the first 7 post-injection days.

Eligibility Criteria:
Inclusion Criteria:

* All adult clinical patients of Emory upper extremity surgeons undergoing injection for treatment of the following who are willing to participate in the study will be included in the study: Tenosynovitis of the upper extremity, including but not limited to, the shoulder, biceps, elbow, wrist, thumb, carpometacarpal, midcarpal, elbow, and small joints of the hand.
* Between the ages of 18 years and 95 years.
* For trigger finger: patients with a diagnosis of stenosing tenosynovitis based on a history of triggering and the presence of tenderness over the A1 pulley upon clinical examination. All patients, based on the Quinnell grading of trigger finger will be included.

Exclusion Criteria:

* Patients who are minors, vulnerable subjects, or who are not willing to consent to participate in the study.
* Allergies to glucocorticoids, current daily use of glucocorticoids or strong opioids (morphine, fentanyl, hydromorphone, ketobemidone, methadone, nicomorphine, oxycodone, and meperidine), severe diabetic neuropathy of the hand influencing pain perception, rheumatoid arthritis, and neurological or psychiatric diseases, potentially influencing pain perception.
* Subjects who, in the opinion of the investigator, may be non-compliant with study schedules or procedures.
