Hello dear and thanks for the query
ASO titre high value i.e. more than 200 indicates Rheumatism
. You have to take it seriously.
If this is associated with joints pain, history of long term fever and throat infection
than the fever may be Rheumatic Fever
Please consult your doctor as soon as possible so the the growth of rheumatism ca be stopped and treated. You can continue with Homeo medication but in such a high value of ASO, you should consult your physician for further investigations and treatment.
