Hi, Im a 52 year old female and for the past 6 months Ive been hearing my knees make this squisging/ rackling noise when I bend them, when I walk up or down the stairs!..I know this is not normal, just wondering what you can tell me..I will be visiting an orthopedic but in the mean time , is there anything I can do to get rid of this noise?...they don t hurt, I exercise on a regular basis, and Id like to continue that, just without all the NOISE!!..Thank you for your help
