<s>[INST] hi,i am surendra 38, iam suffering from impotence since last 1 year , for that time i was a chain smoker but not today.i do exercise from one month and i feel groin pain.my marriage life is worst. please advice what can i do for impotency and groin pain. [/INST] Hi, You need to stop smoking completely as smoking is one of the cause for erectile dysfunction. I suggest you get checked your serum sugar level and measure your blood pressure as well to exclude diabetes and hypertension as cause for ED. If you have anxiety history than it is also aggravating factor for Ed. Practice more foreplay before sex and Tadalafil can be taken 40-60 minute before sex for short duration. If you are obese than loose weight. Intraurethral injection of alprostadil also can be beneficial. Kindly consult sexologist for detailed discussion of all these. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Parth Goswami, General & Family Physician </s>
