Brief Answer: You should go under prostate biopsy. You should be visited by a cardiologist. Detailed Answer: Dear Sir, Thank you for using HCM. Now that you have detected this problem , you need to face and follow the diagnostic and treatment steps one by one. So first of all , you have to do the prostate biopsy, which is needed to make a sure diagnosis. Depending on its response you will consult with the oncologist (if it results to be a malign tumor) or urologist (if it is a benign enlargement of prostate). Regarding your chest pain , it may be caused by low blood pressure , and reflector tachycardia (high heart rate) stimulated by such actions such as urination, defecation , the change of the position etc. Also the burn and difficulty on urination may cause tachycardia and chest pain. Nevertheless you need to see a cardiologist to exclude more serious causes. Hope this is helpful. Let me know if you need more clarifications. Otherwise please close and rate the answer. Kind Regards, Dr. Juarda
