<s>[INST] my 22 yr ols son has had pneumonia 2times in the past 10 months, last month at work - (a hospital thankfully) he passed out was taken to the ER and a ct was done to find out he has a hole in the upper lsft lope, and hi heart rate was down to 23.  Doctors did nothing about the hole, and told him that it was Spontaneous pneumothorax, he has also seen a cardiologist that found nothing. He is now having the same pain he had but now it is on the right side.  He dose smoke on occasion not an everyday thing and he told me he is not doing anything else, he has no history of pot smoking or other types of drugs.  I have no reason to think is not being staight with me, but I do realize he is my son and may not want to tell me everything [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Pneumothorax can recur in the future. So we should definitely rule out pneumothorax for his right sided chest pain. So get done chest x-ray and CT thorax. If both these are normal then no need to worry about pneumothorax or other lung disease. Tell him to apply warm water pad on affected areas of chest. Take simple painkiller like paracetamol or ibuprofen. Avoid heavyweight lifting and strenuous exercise.Don't worry, he will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks. </s>
