What is the exact issue of my health?

Hi doctor,

I am an 18 year old female. I am suffering through a number of physical issues since two years. At first, it all started from sudden loose motion. I often got admitted in hospital for this reason. I visited many reputed doctors, but none of them was able to reach any conclusion. At last I was declared celiac, however, it was not the case. Suddenly, without any medications my loose motion has stopped. It was weird, but I was relieved. Soon after two to three days my right chest started hurting a lot. I could not walk, breathe or sleep. I got an x-ray done and it revealed that I had pleural effusion in my right side of chest. Doctor took out 20 mL of urine colored liquid and sent it for laboratory testing. My ADA was high, but malignant cells were not present. So, the doctor reached the conclusion that I have closed TB. I took the TB medicines for four months. I had very ups and downs in my health in those months and suffered through loose motions often.

I changed my doctor for a second opinion. He said that I have major swelling in my lungs and it can get worse if I inhale air pollutants as I was allergic to smoke and dust. He told me to get a good amount of rest and not to climb stairs or walk much. At first, I daily had mild temperatures and had shortness of breath the whole day. I thought I was getting better, but one day suddenly my ankles, upper area of foot, side and back of knees, front of the elbow and my back started aching badly. I suffered through this pain for days as I thought it was normal a body pain, but the pain got worse. I had severe weakness and often had floaters in my vision. I also lost weight and now I am underweight of 42 kg with a height of 5'4". I could not walk or climb stairs as my feet tremble a lot with tremendous pain. It was as if I am not in my senses. I had an eye infection. I got a small pimple like things all over my shoulder and back. My breathing problems got worse. I visited my doctor and he said my lungs are getting worse day by day and a certain disease will get activated if I push myself hard. He also said that I cannot continue my studies this year. I have to rest properly, however, he said that I can walk until I face any abnormalities in my breathe. But, I cannot walk for five to six minutes without taking rest. It means I can only wander in my house a little. It is just ruining my life. I have attached my current medications list. I cannot understand what is this about. What is the exact issue with my body?

Thank you doctor,

No, my doctor did not tell me to go through all these tests. However, I had liver function test and the doctor said everything is normal. But, I have slight infection and ADA was 85 something. Is this all something to do with COPD as I have major lung issues and breathing problems too? I cannot walk or do any kind of physical activity. I sleep almost throughout the day. My feet and hands tremble a lot. The thing that draws my attention most is that my face looks fat and the body is relatively thin. It is a kind of swelling, but it does not hurt and it is not stiff. The body pain is still there. I can barely walk. What probably causes all this?

Thank you doctor,

I remember that I took one more medicine first with Combunex Rcin and Helirab, it was Veloz. But, it was removed from the prescription after one month. One surprising fact is that the urine colored liquid from my chest area disappeared within 20 days. The x-ray came clear after 20 days of treatment. The liquid took out was only 20 mL and 75% of my right chest showed white in the x-ray. The last x-ray taken was 20 days ago. It was clear, but the lungs were expanded or more accurately swelled up unusually. And for other tests, I asked a number of times to my doctor, but he always mentions only x-ray and blood tests. He says there is nothing big. We are just giving this treatment to prevent anything big to happen. He makes a big deal out of this disease, but never mentioned exactly what the disease is. He says I am allergic to pollutants and these are damaging my lungs. He says that certain disease will get activated and my life will get spoiled, although I am not sure what this disease is. May be he refers to TB or pleurisy or COPD. All that he mentions is that I am allergic to dust and other pollutants.
