Fungal infection. For fungal pneumonia​?

I've had this poor health condition for over a year now. About a year ago I traveled to a few different places away from where I live and I fell I'll immediately. Since that sickness I've not regained myself. I took malaria, thyroid function test, HIV, glucose level, hepatitis A B C, FCB, All these test came out fine. I noticed I've been battling with yeast infection most of my life. My inner thigh and scrotum is always itchy. Recently I consulted ​a doctor who suggested​ I must have visited a place during my travels which is polluted, thereby exposing me to lung infections like pneumonia. Judging from the signs I've  noticed lately such as excess weight loss, pale skin, lower rib n chest pain, wheezing while breathing, chills and night sweats. Also stiff neck and migraine, bloody phlegm. He prescribed treating fungul pneumonia judging from my years of yeast infection. I need help with the right advice and prescription for fungal pneumonia​?
