Sorry to hear about that man.
Have you had your testosterone levels checked?
As the other stated, I am not a doctor, but I think having the load of getting your body enough oxygen for the entire body resting one lung might play a part in it.
Whats your doctor say? Blood and Oxygen levels definitely play a role in getting the Flagship up cause its essentially a muscle. If you are having issue with blood and oxygen circulation that will definitely play a role in that too for sure.
I am 36 and was found to have low testosterone. For my age it should have been within the 300-400 range. I was in the 230 range. Having that deficiency of the hormone plays havok on a males body. Moods, Energy Levels, Erectile Dysfunction, Muscle tone and size, etc. I was put on testosterone replacement therapy.
Basically I take 1 injection a month of Testosterone Cypionate (same .... the body builders take). After about 2 months I started feeling better. Sexual Arousal improved as well as frequency, Mood was getting better, Focus and concentration improved.
Keep in mind I was still smoking though. So I still had the side effects of a smoker. Once I gave it up, I did notice that my erections would be noticeably improved versus when I smoked. (Lack of Oxygen in the blood to the muscles).
Talk with your Dr. I wouldn't place all your hope on the
vape but it will improve some aspects of your life for sure. You have nothing to lose but the money invested in the kit you get. So give it a shot.
