Your not alone. I've been through that nightmare. I've been able by the grace of God to get rid of the sinus infections. I've also found a way to decrease the night sweats which suck immensely. Just do yourself a favor and go to a hematologist. The key to all of this is the blood. Have them check you IgA, IgG, IgE, IgM. 10-1 your stomach hurts because your IgG antibodies are out of range, in my case mine were, that effects the brain and the intestines, causing a sensitivity to light causing stomach pain. check out a lab named cyrex. A standard blood test doesn't check the array of antibodies. Why I do not know. prob money. . I've lost so much weight. My nodules are under my jaw, groin bilateral and neck. I have two solid tumors in my thyroid lobes the right is larger than the left. No one wants to get sued for negligence, in my case. My IgE levels are always high despite not being around allergens. it's unfortunate that we have the science but don't apply it. Defiantly see a hematologist and an immunologist. I've been through the ringer w docs who did everything but, what they should have done. fortune for me I'm a medical researcher. pay close attention to your liver, kidney function. Sounds gross but the clearer your urine the happier your kidneys. If you are taking any antihistamines, stop, stay away from OTC anything for now. Until you can get to a doctor who knows what tests to give you, I've found that for the sinus, a dab of eucalyptus essential oil (not synthetic) on a q tip under the nose,(smells like Vic's ) helps at night. Drink a full glass of water before bed. the night sweats are caused by the fever that takes place when your body tries to heal itself aka the reason we all sleep. Boiron makes a fantastic line of homeopathic OTCs been staying alive all these years w their products. The body needs rest to heal, with your constant fight flight feeling your hormones are dragging you to hell and back. Think of it as starting at zero and beginning again. Sinitus by Boirion can be found at CVS, Quitude will help you rest. Allopathic doctors won't tell you that. So while you wait to see a hemotolgist and an immunologist , try that. And for whatever weird reason I've found that if I massage my feet at night with Almond oil , I feel better the next day. I don't know why. Also have the doc give you a test called Cytochrome P450, get a read on what your liver enzymes are doing. Most scholarly articles are now gearing towards the bodies way of healing itself via enzymes and proteins. Keep me posted after you've tried some of it. I know the disorientation and rag doll effect of doctors and appointments, I also know that I've succeeded when they haven't, I wish you all of the best and good health.
