Just relating my similar experience. I have had a sore upper throat, very bad sinus pain, postnasal drip (last yr it was often so thick I couldn't breathe), nausea, etc. almost every day for over a year. The nausea overwhelms me - it feels like my whole head is very sick and it centers in the throat. I also get headaches and am sensitive to light.
I also have swollen glands (slight) on the right side of my neck. I tested negative for Mono and STDs. My cholesterol, blood are very good.
I had sinus CT scans last yr and they showed all my sinuses were filled but not infected. I took Biaxin which didn't help and Amoxicillin but after 6 days of it had hives and have had them ever since 11/20/04. I also get bad chest pains on the right side a few times per week and it often radiates up my throat and ears. I get the pain across the bottom of my ribs and in my stomach.
I'm seeing an ENT and Allergist. The ENT doesn't think anything of my scans and ordered different scans and a head MRI (she's concerned about the upper palate pain). The Allergist thinks the hives are from the Amoxicillin but are now Dermatographia (skin-writing) and thinks the pains are Acid Reflux. I have been researching that and think it could be true - I have often had pain in my stomach after eating large meals (esp Mexican and Italian) and after drinking pop or iced tea. I think I may have LPRD and am going to try modifying my diet and getting more exercise while waiting to see the doctors again, and am going to mention this to my ENT as I read that GERD and LPRD can cause sinus and throat problems.
Well, maybe some of that relates. GL!!!
As you know postnasal drip is drainage from your nose and sinuses dripping down the back of your throat. You may be swallowing a lot of this mucus into your stomach. It is certainly possible for this to cause your lack of appetite. This would also explain the way you feel in the morning with the nausea and
This may be a long shot, but I have had some of the same symptoms; My nose will stop up for a while and I will have extreme pain; when it unstops, I have massive amounts of clear slimy post nasal drip that almost strangles me. ONce I get it out I don't have the pain any more, but get the nausea, etc. In doing research, I ran across some information about cerebrospinal fluid rhinorrhea, which is fluid that leaks from around the brain into the nose and is more common in someone that has had a head injury or surgery. I think it is supposed to come out the nose, but even when I have an active sinus infection, my is mostly postnasal drip. You can buy glucose test strips like used to test urine for glucose (diabetics) and test the mucus. I don't think that ordinary mucus is supposed to have glucose in it, so if it is positive, it may be a possiblity. It is not the main test used to detect this, so you would need to see your doctor. I bought some of the strips and sometimes mine tests strongly positive and sometimes not at all. My husband's never does. I am going to check this out with my doctor.
Again, I am not a doctor, just someone who has had a lot of sinus problems, and done a lot of research, so like I said this may be a long shot.
