Knee pain and mri said small cyst that was 'ok'. was treated with bursitis with a cortisoneshot 4mon ago. i don't want another shot, what is the cause?

More info. needed: It's difficult to answer your question with that limited amount of information. The most common cyst around the knee is in the back (popliteal area), called a baker's cyst. It can be a sign that there is a problem within the joint (arthritis, cartilage tear, etc.). Bursitis can occur around the knee, but usually outside the joint. Consider another visit to your doctor for an exam and more koptions.

Need more informatio: I need more information if the cyst is a baker cyst this usually occurs when fluid goes out the back of the knee. This is usually because of some problem inside the knee. What else did the MRI show? Bursitis around the knee is actually outside the knee. What type of percentage was it? Bursitis would be because of knee pain when the MRI is negative. You therapy, heat and ice and exercises for the knee so you don't need another shot.
