Hello Doctor.
I am 21 years old and I weigh 50 kg, suffering from severe pain in the bottom of my back and the pain increases with stand on my feet and walking, and bent to sit and rest, Is there a cure for this pain? Do I need surgery?
And for your information I have been practicing masturbation! Does he have a negative impact on it?
I hope you to respond to, because I need your tips.
With many thanks ..
