* It is recommended to have a look at < < Handbook of Laser Blood Irradiation Therapy > > (ISBN 780194-806-8). Low-intensity laser irradiation is indeed effective in improving hemorheology and microcirculation, and after years of clinical research, low-intensity laser irradiation at 630-780nm has no adverse reactions to the body, which is a safe physical green therapy.
* It is suggested to take parents' medical records to the laser specialists in regular big hospitals (all hospitals above 3A) for further consultation, and formulate a scheme of low-intensity laser irradiation combined with drug treatment. There are many semiconductor laser therapeutic devices on the market, so it is recommended to purchase medical devices approved by the state through formal channels so as not to delay the illness.
