Just want to get this out to you guys...We put a lot of stress on our joints as it is.With that being said, Do Not Take Levaquin if prescribed by the doc. This strong antibiotic causes weakening of the tendons and ligaments. A trashed knee and a hurting elbow had me sidelined for awhile and I'm still not to 75% I feel.. So just as a caution to you guys, if you get a respiratory infection or any type of infection for that matter do not let the doc prescribe LEVAQUIN as your antibiotic...There is a class action lawsuit out now..Just putting it out there...Peace...
