Levaquin has been associated with soft tissue rheumatic problems particularly tendinitis. It is not associated with a true arthritis (joint specific inflammation). It is often difficult for patients and non-rheumatologist physicians to distinguish the symptoms between an arthritis and tendinitis. It is difficult to determine how frequent this occurs as most cases are mild and self-limited and thus go unreported.
