| Compartment syndrome and nerve injury may be caused by tissue swelling from trauma associated with tendinitis. Inflammation of the lining of the tendon sheath (tenosynovitis) often accompanies tendinitis. Chronic tendinitis can weaken the tendon and lead to subsequent tendon rupture. Inflammation in tendons of the hand may cause the thumb to extend (de Quervain's disease). Fingers and/or the thumb may be hampered in movement by swelling of the tendons, which creates crepitus or catching (trigger finger). |
