....for about 4 weeks now. It has all the signs of mono. Severe sore throat, swollen lymph nodes (hurts to turn his neck), very large canker sore in the back of his throat and excessive tiredness - sleeping 12 hours at night and taking naps during the day. There is also a bit of a feeling of fullness on his left side under his ribs and that's where the spleen is, if I'm not mistaken. Mono will affect the spleen. When he went to the doctor last week (I didn't go with him), I asked them to test him for mono when I scheduled the appointment. They didn't and said that with mono you only treat the symptoms anyway, so they wouldn't be doing anything different. I understand that. But, he's been sick a lot since this summer and everything he gets hangs on for weeks. If it's not mono, I want to know what's going on with him that he's getting sick so much. Insurance won't cover testing for vitamin deficiency. That is just nuts. He has vitamins, but was bad about taking them. I told him to put them somewhere he would remember and he did. I also put him on B12 and folic acid. I'm going to see our doctor this week and am going to talk to her about it some more.
