Hello Dr, I am facing a set of problems off late though I am not sure if all of them are related. I am 30 year old software employee, married with a 5 year old kid. Back pain and weakness: Blame it on long distance daily to office or wrong postures while doing various things in a day. But end of the day I face lower back pain. Also, extremely tired at end of the day. Sometimes, I pass urine very frequently during the night. Say like 7-8 times with a gap of 5 mns between each time. Lack of concentration: I am unable to concentrate on any work at hand. Say, when if I start reading a book I immediately get distracted and leave the book in middle. This happens in any work I am doing. My mind is constantly changing gears on something else. This is leading to irritation and frequent mood swings which others around me do not understand. Sexual activity: I should admit, at a point of time I was porn addict. Off late I am not able to perform well during intercourse. The erection doesn't long enough. This is leading to embarrassing situations and also taking a toll on my confidence. God forbid, there has not been an adverse impact on my job/relationships thus far. But I am afraid, I am not feeling as confident as I always used to be. Please advice.
