Hello,
Cause of chest pain and left arm pain in a cocaine user can be indicative of developing a cardiac problem like arrhythmia,
cardiomyopathy, CCF, endocarditis.
You are suggested to get him physically examined & get CBC, urinalysis, ECG,
echocardiography, X-ray chest, stress tests,
lipid profile is done to detect the pathology causing the symptoms & discomfort.
Sometimes, the heart may not show any pathology but the lungs get affected by cocaine users. Cocaine-induced chest pain may occur due to
pulmonary hemorrhage, pneumothorax, pneumopericardium or
pneumomediastinum.
Get him physically diagnosed & treated at the earliest.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
