Well I saw the movie "fault In our stars" , WHY IN THE F DID I WATCH THAT? It made me notice that I have. Actually been having this weird pressure above my left knee for a while, also I'm afraid it has spread to my lungs because I've been having constant chest pains. As u all know I go to the dr a lot , but I'm not going for this cuz I'm scared, I read that it's more common in taller kids who are growing, I'm SHORT! I'm 19 and I've been 5'6 for the longest....also my apetite is till fluctuating a lot and I pretty much feel like crap everyday still...so idk. But I'm not going back to the dr...... If I do have it then oh well.,,,,,gonna have to kill me I'm so tired of this... Also just hawked up some metallic tasting sputum with a Little blood in it. But I so have allergies but can any of you know share what u kno about this terrible disease ??
