Hi, My husband has got chronic cough. We treated it with antibiotics few months ago. The cough was fine but he started to shiver at night with high body temperature. He doesnt feel feverish but body temperature is high. Once the episode of shivering with high body temperature was finished, the cough re-occured. Now again we got him treated for cough. The cough was fine after which now he again started to shiver-High body temperature at night. All major tests are negative which include TB, H1N1, HIV, Bronchitis. Xrays, MRI CT Scan, Ultrasound all normal. Little enlargement in Spleen which doctor said is not to be worry about. Kindly suggest.
