Parenteral pentazocine abuse leading to muscle abnormality: A case report

Abstract

The injection of drug of abuse into muscle tissue leads to myositis, pain and ultimately fibrosis, atrophy and may be contracture of the specific muscle/s. Cases reporting the muscular side effects of intra venous (IV) drug abuse are few and this particular complication of drug abuse is not very well documented. We report a patient with myositis leading to atrophy of the shoulder muscles and following this the patient developed limitation of movements.
