I Have Been Taking Osteo BiFlex For About 15 Years

I have been taking Osteo BiFlex for about 15 years now. I started taking it for my knee problems and I was having finger joint pains also at same time. Knees were worse at that time. After taking Osteo BiFlex for 2-3 months, I noticed distinct reduction in my knee pain, and I could go up and down stairs with ease. I also noticed that my pain in finger joints went away.

Some time later 2-3 years, my liver readings at my annual physical were higher than normal. My doctor kept on testing me for that. It consistently was slightly higher than the max. My doctor had me go thru a bunch of other lab tests, without much success in finding the cause. After about 8-9 years of testing, my liver tests stayed about the same, not getting any worse.
Recently I saw that some other patients using Osteo BiFlex had elevated liver tests.

My question is should I be concerned about it? Should I stop using Osteo BiFlex for a few months and see if my liver tests eco me normal.

I am 72 years old and my other problem is psoriasis and I take weekly injection of Methotraxate 90 mcc. And I am border line diabetic taking 1 pill daily 500 mg of Metformin for about 18 months.

Any suggestions how should I proceed.

Thanx
