Hi, Welcome to Health care magic forum.
As you describe,according to the genetic factors you have a good possibility if increase in height if it is before 4 years.
Still if you want to try, consult an orthopedic surgeon for the purpose. He will take the
X ray of the ends of the long bones ,if the growth points are active,he will treat you.
I usually prescribe to my patient with such condition, injection of
anabolic steroid one injection,
protein supplements preferably complain, multivitamins, calcium.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods.
Wishing for a quick and complete recovery. Thank you.
