Approximately 3 weeks ago I was nipped by a male mastiff protecting his girlfriend (who was in heat). I say nipped because if he wanted to, he could have done major damage to me, but didn t. Major bruising under my upper arm where where I was nipped a couple of times. Broke skin. Went to a doc in the box where they cleaned and dressed my wounds, gave me a tetanus (?) shot and an antibiotic shot. Took oral antibiotic ( Augmentin ) for 10 days. Saw ER doctor later in case I needed rabies vaccine (he didn t think it necessary since the dog had received rabies shot), and saw physician s assistant two days later. Anyway, bruising has gone, scabs are gone, but hard lump remains. Should they eventually go away or should I see a doctor again?
