"i have &quot;jumpers knee&quot; tendonitis. i play softball and i am a outfielder...i also workout 5 times a week. back in my days i ran track as well...i guess it all caught up to me in my early 30&#039;s ..i couldn&#039;t lift my leg below my knee it was so painful, my sports dr prescribed voltaren and when i used it as prescribed 4x&#039;s a day i saw a good bit of improvement..."
