Hi my husband has had intermittent fever 99.9 to 100.00with dry cough and fatigue mostly at night. He started taking valsartan a couple of weeks ago but had to stop due to night sweats and developing the dry cough. He went to his doctor and was told his lungs sound ok. He has been off the medication for 3 days now. The night sweats stopped. The on and off fever, dry cough and fatigue at night persist. I am worried this could be a sign of something more serious. Any advice would be appreciated. Thank you
