Dear Michelle, welcome to HCM.
creat cannot be 50. pl. check.
u seem to have a respiratory ailment. likely infected.( gram positive bacilli grew in sputum or blood?
if you had symptoms for months , you need detailed work up of underlying pathology.
well TB , cancer, and many more differentials. difficult to say from here...
pl. get evaluated with a pulmonologist/ physician , a thoracic CT scan
, fluid exam etc.
hope you get well soon.
pl. keep me informed on the progress.
would be glad to help.
