Corticosteroid injections


At times, diagnosis of a condition may involve aspiration of the joint and examination of the fluid under microscope. The characteristics of the fluid can help us differentiated between different types of arthritis. Most joints can also be injected with anesthetics and corticosteroids for rapid pain relief. Almost every joint can be injected to relieve pain. These are some of the joints that Dr. Firooz will aspirate and inject:

  • Hands
  • Feet
  • Shoulders
  • Elbows
  • Wrists
  • Knees
  • Ankles
  • Jaw (temporomandibular joint)
  • Lower back (facet joints)
  • Lower back (sacroiliac joints)


Injuries to tendons and bursae is very common and can result from sports or any repetitive movement of our daily lives. If conservative management does not resolve the pain, corticosteroid injection is very helpful for pain relief, and often, healing of the injury.

These are examples of such injuries:

  • Carpal tunnel syndrome (wrist)
  • Tarsal tunnel syndrome (ankle)
  • Lateral epicondylitis (tennis elbow)
  • Medial epicondylitis (golfer’s elbow)
  • DeQuervain’s tenosynovitis (thumb)
  • Subacromial bursa (shoulder)
  • Trochanteric bursa (hip)
  • Patellar bursa (knee)
  • Trigger finger (locked finger)
