I have been having fever from the last 7 days which is going up and down , plus cough too. But before this I was having abdominal pain as I am a patient of IBS and was getting treated for that for which has recovered 90%. Not sure wether this fever is because of IBS , I went to a physician and prescribed some tests like CBC ,WIDAL AGGLUTION , C-Reactive Protein , ESR . My question is that is IBS causing this or anything else . Kindly advise before I take consultation The pattern of fever is like Early Morning - on a scale of 99 f Mid Day - it goes to 100.3 f Late Night - 102.3 f I am energyless and my eyes are burning
