These can present with a palpable defect in the muscle or tendon. However, swelling in the area may make this difficult to appreciate. These injuries sometimes require surgery to reattach the damaged muscle and tendon. An x-ray may be helpful to rule out a fracture or dislocation as the cause of pain.
The most likely cause is an airborne bacteria called Serratia Marcescens. This bacteria is common and generally grows in damp conditions such as those found in bathrooms and kitchens. Serratia produces a pinkish film on surfaces that are regularly moist and subject to humid conditions.he most likely cause is an airborne bacteria called Serratia Marcescens.

S. marcescens may also be found in environments such as dirt, supposedly sterile places, and the subgingival biofilm of teeth.Due to this, and because S. marcescens produces a reddish-orange tripyrrole pigment called prodigiosin, it may cause staining of the teeth.The biochemical pathway for the production of prodigiosin by S. marcescens is unknown except for the final two steps.. marcescens may also be found in environments such as dirt, supposedly sterile places, and the subgingival biofilm of teeth.
