Tendonitis?

In the past few months I've been diagnosed with bursitis and 2x tendonitis in my right hip, tendonitis and meniscus tear in my left knee, and now tendonitis in my left shoulder.

Since I haven't been doing anything differently than usual, I'm wondering if there is a more systemic cause to all this. The only thing I have found is that sometimes tendonitis is linked to diabetes. Has anyone every heard or read about or experienced this?

My sugars were high for a while a couple of years ago, but since they went down I haven't been testing very regularly -- I will check again!

Thanks

I knew it was a long shot, but thought I'd ask. Happy New Year!
