Hi Welcome to HCM
I HAVE gone through your query regarding continued ultrasonography

Dear Mini , I can understand your concern . After all there are some laws of nature
If you are sick you need treatment but not if you are fine . Your sonography results show that your reports come out to absolutely normal , since 4 years .
Why to be continued further for indefinate time ?

I as a Naturopath ,Homeopath & magnato therapist , am shocked about it .
Any way , That is there lookout .
Dear, one thing you have to keep in mind , perfact health can't be achieved by only gulping on medicines and plls,bulky tests .unless you adopt regular life style and food habits and adequate supplements like garlic ,ginger onion , coconut water ,lemon juice with water , turmeric powder with a cup of hot milk at bed time ,bitter gourd is geart antioxidant & anti biotic and regular exercise ,walk ,yoga ,pranayam
Avoid fried, fast foods , tea ,coffee , Alcohol ,mental tention ,anger. Constipation
With all the Above regimen having no side effects and Proper regular exercise from head to toe , Walk , yoga , pranayam deep breathing & proper rest , sufficient sleep can boost immunity , and strengthening our system ,paving way for perfectly healthy ,disease free , blissful life ahead .
"The magnitude of the survival advantage from improved nutrition & activity level can even be greater than the magnitude of the treatment effects being targeted in current clinical drug trials ."
, Progress is not just creation of more and more drugs but we should be able to depend on them only at the time of emergency.
In my view We should be able to curb the diseases at their root which is possible by resorting to the drugs created by the nature itself ,which are withourt side effects
In my point of veiw . You can talk to your treating practitioner ,suggest him or take his suggestion regarding your concern .
Hope this helps solve youer query . Take care .All the best

Dont hesitate tio get back if have any further query
