A question regarding gravelly sounding knees?

well, since i do not know how to star something you wil just have to read what i say. glucosamine and condroitin take a while to get going. i have been taking it for like a month and it seems to be helping some. it can also be from arthritis, which i know because i have gravelly knees(hey that is such a good description) and the orthopedic doc said that i had arthritis pretty badly. under my knee cap. so keep on taking the G and C and hope for the best.
