Suggest Treatment For Knee Pain After Taking Spinning Classes During Work Out

Hi, may I answer your health queries right now ? Please type your query here... Hi, I am a 20 year old female, 110lbs..Last week I began working out again for the first time in a couple months. I used an erg (a rowing machine) and ever since then have been experiencing knee pain..took it easy, but yesterday took a spinning class, and now my knees are really hurting..have been icing, but nothing is working. Any suggestions??
