<s>[INST] I am alergic to dust. I had breathing problems since Nov.2011 after replacing a old cotton bed and did some wall painting. I was under treatment with a chest specialist for alergy and chest infection, and the breathing problem reduced but due to over dose of tablets although i do not have much of a breathing problem I have developed internal fever which is less than 100 F which comes down with paracetamol but is persisting for the past two weeks. I have visited another doctor who has given me antibiotics which I have taken for the past 5 days with no positive results. He says I have to do a PFT and cardiac test. What should I do? Please help. I feel very exhausted with to much of medication. [/INST] Hi, You have taken treatment for allergic breathing problem, and later developed fever.But fever can not be due to side effect of any tablet usually given for allergic breathing problems. I would suggest you to record temperature pattern and then consult doctor. There are many conditions like TB/Malaria where particular temperature rise pattern will be present. Get lung function test [PFT] and imaging too ,to rule out infective foci. As fever is there means , there is infective foci in  body. So consult doctor for thorough clinical examination. Take care.
