I understand your feeling and also your concern towards your health.
Suffering from frequent cold and headache and body aches may be because of lack of good immunity. You need to develop your immunity by having eggs count of 2 and also start having chawanprash everyday. You will see improvement by yourself. And you till then you need to do is to avoid cool breeze, having cold drinks, covering your nose and ears while traveling.
That's all you need to do. And your headache might be because sinusitis. You need to consult a ENT Specialist.
Frequent cold cough is a common problem today due to low immunity, it can be very well treated with Homeopathy permanently, if you go to allopath he will give you long intructions of dos and dont, like avoid cold things like cold water ice cream etc etc, in Homeopathy we have very good medicine for immunity, if you eat cold things or weather is bad then also you will be fine, six months to one year of regular treatment is required, you can discuss detail in whats App - eight six zero two double zero five triple zero.
Feel free if you have any query.
