 [ Symptoms ] i keep getting sinus drainage that leads to a full blown cold why can not i get a shot of penicillin anymore [ Disease ] i found that if i do a nasal rinse on a regular basis that i have way fewer sinus problems you could try a nettie pot or possibly just a saline solution sprayed up the nose if you ask at the pharmacy counter they can recommend not just a saline spray but also other nasal rinses that will keep the sinuses clear of all the junk that accumulates there good luck
