to PS 150,
Have you tried Glucosamine Sulfate with Chondroitin for the arthritis pain and tender joints that you are experiencing? I have a squeaky knee and tender fingers at times (and I am not 28 either)and I swear by the Glusosamine Sulfate with Chondroitin. It helps joint comfort and stability. It takes a few weeks before you notice an improvement but it does work!!! Been using it for years and FINALLY my orthopedic doc recommends it. Not sure if I am allowed to recommend this on this board. I am a nurse just thinking about your problem. pm me.
