My Mama always said the ONLY thing that don't hurt as you get old is your HAIR! I am finding she is right! Pains comes suddenly out of nowhere and hurts for days, then go away...... sometimes.. I got up one day from lunch and BOTH of my knees felt like they were "rusty joints".. That was about 4 years ago and they have HURT like Heck ever since! If I don't take Aleve every day, I can hardly bend them for the pain. I hope your solution is as easy as mine. 1 Aleve a day and that is IT!
