I'm A 28 Year Old Female, Smoker, Occasional Drinker (less

I'm a 28 year old female, smoker, occasional drinker (less than one time a month), 3 weeks afo I was put on amoxicillan for an ear infection. Then on Halloween I was put on prednisone, albuterol inhaler, tesslon pearls, and tussin with codeine for bronchitis. This last week I went back in and was place on amoxicillan again for an ear infection. Daily I take 50mg of Lamictal. I still have a phlemy cough, stuffy/runny nose, migraine, and now my soft palate is bright red (almost rashy looking), painful, slightly swollen with small white spots. I need some type of relief...PLEASE help!!!
