antibiotics suppress the condition and make the immune system below par - vaccines do the same . Sneezing is an allergy and allergies are down to a depressed immune system!. 2 suggestions - one; use Nat Mur 10m to remove problems due to previous medication -allopathic or homeopathic - and wait to see result 2/3 wks. Two ; use Nat Sul 1m or 10m - I once cured a man who was allergic to his own dog! with this .
Incidentally the use of silica on a repeated basis , that only pàlliated the symptoms for a time shows how homeopathy -as well as allopathy can be used to suppress and drive symptoms inwards , worsening the condition of the patient !!.
