Sorry to hear about your diagnosis. You didn't clarify details about your PCP/PJP pneumonia
. The fact that you are requiring so much oxygen to maintain your saturation around 89% makes me feel a bit worried about the treatment you had. You should be on treatment for at least 3 weeks on high dose antibiotics with some steroids
for a week or two.
This pain could be due to pleurisy
or a collapse lung called pneumothorax
on the left side which also can cause low oxygen saturation
Ideally you should go to the ER to get it checked out urgently. There are other conditions in the lung which can come along with HIV
infection mainly when your CD4 count is below 200. take care. You should have your treatment, HAART etc very religiously making sure that you take them everyday without fail ideally at the same time of the day. If you are careful about this , your viral load
should go down to minimum and have a normal life. It is important to make sure you are no expose to the risk/take protection from where you contracted the virus, as many people could get a second strain from the existing one.
