Does Using Glucoasimine Cause Growths On Skin?

Hi, may I answer your health queries right now ? Please type your query here...I was told my my dermatologist to discontinue taking glucosamine. She told me it can cause the skin to grow scaley like growths. I was given a chemo cream to apply daily to get rid of 2 areas that had this growth.

Since the discontinuation of using 2 Glucosamine Chondritins daily...I am having a lot of discomfort and stiffness in joints like I did before I quit using it.

Is this true about Glucoasimine causing skin growths?
