Almost 6 days since dx w/pneumonia, starting antibiotic.Still have 101 fever,severe cough w/phlegm,chest/back pain.Is this normal?

Not normal : It sounds like you need a re-evaluation to make sure a complicating feature to this infection isn't at play or that there isn't an alternative diagnosis beyond just an uncomplicated pneumonia. ...Read more

Nosocomial pneumonia, male (age 60), fever 103 for 3days. Antibiotic started 2days ago (augmentin, azithro). When will temp. normalize? Is it serious?

Nosocomial pneumonia, male (age 60), fever 103 for 3days. Antibiotic started 2days ago (augmentin, azithro). When will temp. normalize? Is it serious?

It can take a while: The condition sound serious. Nosocomial (hospital-acquired) infections are usually worse than "walking pneumonia" of the community. You'll be on antibiotics for 7-10 day (avg), & barring relapse, you start to feel better around that time. The fevers can persist until then, but usually dissipate in 2-3 days. If fevers persist, talk to your doc about changing antibiotics. Any lung infection is serious. ...Read more

?drug resistant: Under circumstances, do not delay, and contact your doctor immediately. Not every infection responds to an antibiotic, and you might have a drug resistant organism or even a problem secondary to a viral organism. Since you are not responding, you need attention now. ...Read more

Why am I given a 2nd antibiotic for pneumonia even though have no cough, no fever? Should I take it? Recent quit smoking. Chest pain/short of breath.

Pneumonia: You have not provided enough info to allow an intelligent comment. If you have questions about the manner in which you are being treated and cannot get straight answers from the doctor you are seeing it might be very beneficial for you to get a second opinion. If you can contact an infectious diseases expert that might be the best avenue. ...Read more

Day 10 pneumonia, 2nd antibiotic+steroid,fever,chills,sweats,joint pain now gone but chest still rattling/wheezing/gurgling. PF 55% best. Recommend?

Day 10 pneumonia, 2nd antibiotic+steroid,fever,chills,sweats,joint pain now gone but chest still rattling/wheezing/gurgling. PF 55% best. Recommend?

Mgt: I would suggest another visit with your PCP. You may need to use an inhaled steroid combined with Albuterol/serevent more often or they may increase the dose of the inhaled steroid. They will also assess you for the use of oral steroids. Another chest Radiograph may be obtained at that time. ...Read more

Doctor thinks I have pneumonia.Started antiobiotics. Fever stopped. Heart rate very high (85-100). I'm worried, is it normal?

Doctor thinks I have pneumonia.Started antiobiotics. Fever stopped. Heart rate very high (85-100). I'm worried, is it normal?

See below: It would not be unusual for you to have a mild to moderate increase in pulse rate during early treatment for pneumonia. 85-100 is not a very high heart rate. The fact that your fever is better suggests your antibiotic treatment is effective. If you are feeling better don't worry about a pulse of 85-100. It will return to your baseline after resolution of your pneumonia and any deconditioning. ...Read more

Diagnosed with pneumonial & fever 40 celcious, hospitalized and treated with antibiotic, till now, fever still, but drop to 37.5 - 37.9, shall i worry?

Hard to know: It sounds superficially as if you are getting slowly better. Fever is a result of ongoing inflammation which is necessary to help fight the infection. It may not go away immediately. You should discuss this with the doctor treating you. ...Read more

Child has pnemonia still low grade fever while antibiotics is that ok?

Child has pnemonia still low grade fever while antibiotics is that ok?

Depends: Continued fever with pneumonia while already on oral antibiotics can be of concern. It may be indicative of a pleural effusion (fluid in the lining of the lung). It can also just mean you need to give the antibiotics more time to work. I suggest discussing this with your doctor and getting a chest x-ray. ...Read more

Child has strep and very mucusy cough that began after starting antibiotics, could this be pnuemonia? Still has fever after dose 3 of antibiotics

Child has strep and very mucusy cough that began after starting antibiotics, could this be pnuemonia?  Still has fever after dose 3 of antibiotics

See doctor now: it is not clear that your child has strep pharyngitis or not? Was it confirmed by rapid strep screen? You said he had 3 doses or 3 kinds of antibiotics? Any way he is still running a fever. He needs to see the doctor ASAP. Maybe more blood tests or CXR need to done to make a correct diagnosis and followed by appropriate treatment. ...Read more

On 10-4-12 i was given a flu shot & pnemonia inj in arm. Developed cellulitis within a day . Finished antibodic but arm still looks terrible?

Local reaction: The overwhelming probability is that you reacted adversely to something in the injected material, whether the antibiotic or the carrier. If it is not getting worse, time is the great healer. Warm compresses at this point might be helpful. On rare occasions this may represent infection from a contaminated injection. If so and you are getting worse, see doctor asap. ...Read more

Why does pneumonia cause fever?

Why does pneumonia cause fever?

Chemicals: Infections cause the release of chemicals ( interleukins) from white cells. These chemicals are extremely potent and mediate a variety of host responses to infection including raising your temperature. Your body seems to fight a bit better at warmer temps and some bacteria don't do as well. ...Read more

Brother had stroke, is in coma. Not waking up. Treated for pneumonia and fever. Happened Thursday night. What should I expect or prepare for?

Depends: This all depends on how large the stroke was and which parts of the brain were affected. Also, getting pneumonia on top of that likely complicated things. I wish him well, but unfortunately, you are at a "wait and see" point in his care. ...Read more

My 4 year old daughter has a slight case of pneumonia and her fever now ranges between 99-100. Is this normal? it used to be between 102-104.

My 4 year old daughter has a slight case of pneumonia and her fever now ranges between 99-100. Is this normal? it used to be between 102-104.

Fever: Typically after 48 hours of antibiotics doctors like to see temperatures below 100.4, if not we need to re-evaluate the treatment and diagnosis. 99-100 is acceptable, but also be looking at her other symptoms.... Her respiratory rate, her energy level, her cough, if those are not improving that is cause for re eval as well. ...Read more
