<s>[INST] My husband has a bad cough and back and leg pain.  He never complains or is sick.  About a month ago he did get the flu pretty bad missed a week of work.  He has never missed work in 25 yrs.  He also is working nights .  Today he woke up and asked for motrin because he cant get comfortable he is very uncomfortable.  I am worried he may have phnemonia or something worse.  He doesnt want to go to doctor.  should I be worried? [/INST] Hello read your concern and I think that your husband should see a lung specialist. If I were his doctor I would do some blood testsBlood countCRPChest X-Ray and if he is a smoker or ex smoker maybe a chest CT and then a Spirometry test. PPD testSputum smear for TB.EKG it is again a pneumonia it is very important to know the reason it is come back after one month? The pulmonologist will help you further. Thank you Chat Doctor.  </s>
