My friend just recently got over a bad case of Lobar Pneumonia. Her heart stopped for several seconds.
l was wondering if it is possible she could get it again, but it would be even worse than last time?
She is showing all the same symptoms as before and the medicine she took is not working.

Yes, l have had pneumonia 4 times. And, l am a respiratory therapist.

Yes, especially if she did not follow the doctor is advice FULLY!
Many people make the mistake of taking an antibiotic until they feel better, and then they stop. Not Smart!
They weaken the virus enough to feel better, then stop taking the drug. Then the virus grows back even stronger!
Have your friend go see a doctor and this time do EXACTLY what she is told to do for as long as she is supposed to do it!
This is NOT worth slipping up on.

Yea It can come back if not properly treated the first time, the antibiotics she was givingg the first time my not have taken and she may need something stronger or she needs a new doctor to re-check her.. l will be praying for her to get better good luck and l hope this help a little

l am not a doctor, but I've heard that pneumonia does come back, esp. if you do not take all your meds, plus each time you get pneumonia, it weakens the lungs. So be sure and get some breathing exercises and ask your doctor what other exercises would be good.
