<s>[INST] Hi I have been diagnosed with pleurisy 2 days ago. The pain has subsided with pain killers and I am on antibiotics. I am fine when I lie still in bed but when I get up I just dont feel right, feel slightly dizzy and sick! Is this a common sympton to pleurisy? [/INST] HelloThanks for posting here. The symptoms you have mentioned can be caused by pleurisy. Pleurisy is an infection of the outer covering of the lungs called the pleura. It can cause pain along the ribs increasing on deep breathing, fever, breathing difficulty and cough. It takes about two weeks to be cured hence you may feel weak and dizzy. Another reason here may be due to antibiotics. Some people do not tolerate antibiotics and have dizziness after antibiotic use. So keep taking the medications you have been prescribed and if you don't feel fine after three more days (total 5 days on antibiotics, you must visit your doctor and get your antibiotics changed. At this point of time just two days after pleurisy, you need not be worried. Just give your body and antibiotics time to fight. Wishing you good healthRegards </s>
