I dont think I did. What is a bone scan?
Thanks for your information There are a few reasons for swelling around your knee. Fluid can fill inside the capsule over the knee or outside of that, and it can be blood or non-blood fluid. Since you haven't suffered direct injury to the knee and it seems you've had this for a while, it is not likely you have problems such as ligament (ACL/PCL) or meniscus tears/injuries (as seen in football/soccer). You could have arthritic knees where the fluid will build up over time, particularly with increased activity. There is a possibility for the bones around your knee to have stress fractures from overuse or infection/osteomyelitis. You could also have some sort of bursitis (inflammation) of the capsule (prepatellar bursitis) or tendonitis/ligament strain. There is also a chance of gout/pseudogout.
Therefore, xrays may not pick up the above situation the way MRIs and Nuclear Bone Scans of your knees can. Bone scans are particularly good in osteomyelitis and stress fracture since those are not seen in regular xrays. Inquire with your physician or a orthopedic physician /rheumatologist about investigating your knee swelling further and see if these additional scans can be of benefit to you. If you have the funds, you may want to try a supplement called Wobenzyme N, which are enzymes that are not meant for digestion but for inflammation in areas of injury (hence, taken on empty stomach), which can be found at health food stores or Whole Foods or even online stores. It does not claim to cure/treat conditions but it may benefit you (and I have found it of benefit for myself in the past). Check with your doctor if you are on any other meds so that you can try that supplement without issues.
I hope you found this information helpful and I thank you for your post. Feel free to ask for additional help. ~RoseMD
