Welcome to Health care Magic.
I have gone through your query.
All the problems you have been facing are definitely not due to masturbation
Masturbation is a common thing and 90% people do masturbate. 2-3 times a day is also not over masturbation.
Masturbation does not cause fizzy vision, hair loss, low back pain
and dark complexion or growth retardation.
The memory loss
you have been experiencing is due to lack of concentration and exhaustion. If you have too much erotic thoughts try to control yourself by keeping yourself busy in other activities like laying or interacting with your family memebrs.
Try to meditate atleast 15-20 mins a day.
Feeling tired and fizzy vision and loss of glow in face could be due to improper diet.
Firstly be comfortable with yourself. Do not think something is abnormal with you.
All the changes you are feeling are due to hormone changes that usually occur at your age.
Take lots of fresh fruits especially citrus fruits and bananas. Take fresh leafy vegetables and carrots. Use almond oil for your hair ( it is rich in Vitamin E
If you are a non vegetarian take chicken or mutton liver( atleast once a week, egg ( Daily) to imrove your memory power.
You do not require any medicines a good diet and some quality time either with your family members or friends would be enough.
Hope you got my point.
Wish you healthy life ahead.
