I have a question about various symptoms that my 8 year old has had. He has been sick on/off for about 6-8 weeks. He has had various infections which we thought were colds, and would run fever on/off. Then was sick for about 7 days with diarrhea. We did take him to the doctor during that time, and they wanted to give it another week and see how things went. The diarrhea stopped. Then he got another respiratory infection, and was sick over 7-10 days. After about 7 days, out of the clear blue he started running a fever around 101. He hasn't had his normal energy level, or his normal appetite. Looking back over the last few months, he has been sick more than he has been well. We did take him back to the doctor again, and they ordered blood work. We are waiting for the results. He is now having diarrhea again, but the fever is now gone. So over the last 6-8 weeks he has had respiratory infections, diarrhea and fever on/off. I would appreciate any feedback of ideas of what this could be. I am hoping for the best, but of course the worst is also in my mind. Thank you for your time.
