Hi S.! My prays and sympathy regarding your Mom, it's one of the hardest things to deal with in life is the losing of a loved one. One of the other is dealing with sick children because we would love to take away their sickness but depend on Doctors, some of which I have to tell you with seven children and having lived all over the country, we've experienced our share of those, shall we say, we'de rather let them "practice" on someone else. I'm not saying your Doctor follows this line but I do wonder why he/she is not asking you to bring him/them in for a throat culture to at least rule out strep! Strep is NOT something to play with and can do a great deal of harm. I'm not a doctor nor state to be but I have a great dis-like for Doctors who treat their patients with less than at least some compassion, let alone concern for instead of just another billing. The rash that you spoke about my oldest is currently experiencing, tremendous outbreaks across his chest and back, even his arms and they can happen it seems, almost instantly, cause him to want to scratch insanely, and then it seems to just go away. We KNOW it is some king of alergic reaction to something, just haven't pinpointed it yet. We did take him to a Doctor that specializes in allergies and when they shot him up and down both of his arms (52 all together), he came back being allergic to just about everything there is, (ie. pollen, dog/cat hair;saliva, weeds, rodent etc). So personally if I was you I would start with having the Dr. at least do a throat culture on all of you. Obviously if you all do have it Amoxicilin is in your future. If your son with the rash comes back negative I would ask for a referal to a specialist in allergies. Also, regardless if you are poitive or not, whenever you have a sore throat or upset stomach, stay away from citrus and dairy products, they both increase your pain and symptoms. Be blessed and I pray you all get healed quickly.
