I ve been taking several antibiotics and cough meds. to treat flu/pneumonia symtoms for a week and a half and I have this constant cough that keeps me awake all night long. I was given Prometh/cod 6,25-10 syp. by mouth every four hours as needed for cough and it doesn t work. I have also tried over the counter Robitussin. Finally out of desperation I have been taking Hydroco/apap 7.5-325 mg tablets, which I had been taking for a Frozen Shoulder I have been battling for over six months. If nothing more, they have made me sleep, so I don t cough. Another thing that has been bothering me, other than the aches from flu like symptoms is the soreness in my mouth. My tongue is swollen (red in color) and it hurts to eat. I don t have the symptoms commonly associated with Thrust . Any suggestions, I don t want to take drugs that interact with each other causes horrible pain and discomfort.
