I have had several injections in the knees, hips, back and shoulders. It depends on if the Miniscus (sp) is torn or not, whether it will help. I recieved relief for about 2 months on my knees before it became to the point of replacements. However I just had a injection in my shoulder and it only lasted 4 days. and they are operating on that on the 13th. Go to A good Specialist ( I had to to a lot of internet research before I found a good one) Good Luck and I hope you find relief.
