<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have had swelling and redness on my left knee for 3 days now, I have also been running a fever of about 100- 101. I have had 2x-rays by ER and orthopedic surgeon both were negative. I was told to rest for 1 week and see how it feels. Diagnosis was pulled tendon. Is this pretty accurate and should I wait and see after a week.  <response>: Hello, You might have developed slight inflammation over the tendon something called as tendinitis. As of now, you can use analgesicsanti-inflammatory combination like diclofenacserratiopeptidase for symptomatic relief. A short course of antibiotics can also be considered. If symptoms persist an MRI scan is required for further assessment. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
