I used to have hay fever in a rather benign way, watery eyes when pulling grass from the garden, but it later developed into the worst discomfort I have ever experienced - a sudden rapid & extreme swelling of nasopharynx, with inability to swallow. Had the usual itching & burning of palate, corrosive hot salty saliva, numbness about the lips, & no air passing in or out through the nose.. It progressed so that I was having these attacks nightly, & had chronic difficulty breathing during the day. I would put my arms into hot water up to the elbows & also press hot wet cloths to my throat & face to try to relieve it. Belladonna 30c used to help at first.. overtime it worsened until I had such severe sinus infection that my gums were numb. Once I rang for the ambulance & they hung up on me. Locum doctors called at night didnt know what to do, & no-one referred me to hospital. It was only after 5 years when I purchased the RADAR software, that I found my answer via the Vithoulkas Expert System. Among the rubrics I chose, was "History of Glandular Fever" - remedy Carcinosinum. I had amazing relief within 24 hrs, feeling of another attack coming after 2 weeks, a second dose, then a few doses over the next 3 years. 10 years later, still no recurrence. None of the sore throat I had daily for much of the year since GF at age 14. I had tried many other remedies & other homeopaths, with no result. Deepest gratitude to Dr Vithoulkas & the developers of RADAR.
