Question about pneumonia?

Ok so a few weeks ago starting about may 14-15 I started getting what I thought was a cold, so I didn't think much of it, then it progressed to where I had a fever of 102.5 and was feeling like I was in a freezer constantly even when it was warm outside (I guess you would call it cold chills ?) and had the worlds WORST headache and then I developed a severe cough and my upper chest started feeling weird I don't know how to explain how it felt, I guess it just felt inflamed idk it would make it where if i took a normal deep breath I would instantly cough, simply a reaction like i had taken too much air but when in reality I only took a normal deep breath, and now i don't even have to take a deep breath, just breath in a little bit as if your was gonna clear your throat, or laugh or anything like that I get the same feeling and instantly cough and now I have to make sure I don't breath in too much so I don't cough every time i inhale, and now every symptom is gone (fever, cold, headache, cold chills) just not the cough and the inflamed feeling in my chest, oh yea and now occasionally I will cough up mucus but not every time I would say about 35% of the time. Today (June 1) got to reading about pneumonia ( I started wandering if maybe that was what I had) I have had pneumonia 2 times in the past, once as a baby in both lungs and once when I was in 2nd grade in my left lung (I'm not sure if my past with pneumonia matters any) and It appears that I have most of the symptoms, the only symptom that I have read about that I do not have is this right here. "In some, the spongy tissue of the lungs that contain the air sacs is more involved. In this case, oxygenation can be impaired, along with stiffening of the lung, which results in shortness of breath. At times, the individuals skin color may change and become dusky or purplish (a condition known as "cyanosis") due to their blood being poorly oxygenated" I don't have the skin discoloring and I am not sure really what stiffening of the lung is so I cant say if I have that or not, but either way that's only if the "spongy tissue of the lungs that contain the air sacs" is also infected, right ? is it possible to still have pneumonia without this symptom? and also, if my other symptoms went away does that mean that I possibly don't have it ? although I do remember specifically when I had it the 2nd time that after a while of having it I felt fine but I still had the cough as I was telling my parents that I felt ok other than the cough because I wanted to go play with my friends (I was a kid in 2nd) and they would say " no because you are still sick" so im assuming that even though my other symptoms went away I could still have it? I can't afford to go to the Doctor, at the moment, if this is pneumonia is there anything that I can do or take that can help me get better without going to the doctor, and also if there is something I can do to confirm that I have pneumonia or not please let me know, and lastly ANY advice that you are able to give will be greatly appreciated.
