I have horrible nights sweats and will soak up my shirt typically and sometimes even my bad. We ruled out Hep A, B, C, any sort of STD, Tuberculosis, parasites or bacteria. We picked up on beta thalasemmia and food allergies to Peanut, Walnut, Soy, Wheat, Corn, Shrimp, and Sesame. I don't know if thalassemia is causing it. I am pretty sure I am a beta thalassemia minor but wanted to share my info about night sweats.
