My son is 4 year old and has been suffering since 4 weeks now. Have tried all medications but nothing has worked till now. Now we have switched over to Homeopathy since 4 days, and not sure how much time would it take to recover. He has been coughing continuously which leaves me worried as his food intake has reduced drastically which has made him further weak. Please help me along with the Homeopathy medicine what further can I do to ensure he gets relief as soon as possible. Need urgent help.
