I have injured my knee previously, but this time the pain is definitely more severe. I have a grating sensation when I walk, often accompanied by a clicking in the joint. I am going to see a doctor, but not for two more days. I am taking extra strength tylenol, which helps the pain a little. I cannot sleep due to the pain and discomfort I am in. I was wondering if anyone has some tips to help me manage the pain until I can see my doctor. Thank you.
