Please advise some homeopathic medicine for 5month20days old son for teething problem. He is not feeding due to pain and crying a lot

A. teething is a natural process and doesn't require any medicine instead massage the gums with a clean cold cotton cloth and cold silicone teether to chew on them there is a loss of appetite during teething so do not force feed occasionally you can give paracetamol to your child if there is a lot of irritation in the gums
