hello and welcome to HCM,
I have understood your son's problem regarding the throat and neck problem.
Since his throat is congested or red as described by you and since he has lymph
node enlargement you need to start him on a course of antibiotic irrespective of the results of the throat swab. You can start him on amoxycillin-clavulanate
combination 625 mg twice daily after food for five days and pantoprazole
40 mg twice daily before food for two weeks. Your doctor will know about these.
Since you are already keeping him off sugar and dairy foods and giving him organic nourishing food, you are in the right track.
You need to wait for a week or two for the lesions to subside and the glands to regress. If however it does not become better you need to consult an ENT/ Dermatologist
so that they can investigate further (endoscopy
and CT Neck) and give you a directed treatment.
take care and hope you get well soon
Dr Sriram Nathan
