I am female, 16 years of age, with muscle pain, sickness, and malaise. My muscle pain includes a sort of heaviness, tenderness, pressure, achiness around my chest (mainly left side), arms, and shoulders (mainly left shoulder). I have been to the ER, through which urine samples, an EKG, bloodwork (they took three viles), and chest X-rays have been determined as normal, although the blood count was a slight bit high in white cells, but I went to my family doctor the day after Emergency, and had another blood test, which was normal. I have some coughing, with occasional phlegm (but it is almost always a dry cough) and some throat problems which make swallowing a little difficult, and discourage me from eating sometimes, and previously, from drinking much as well, as it is strange, and feels like nothing wants to go down my throat, but this is not stomach-related. There is occasionally stomach upset, which feels like an eruption and I must hastily proceed to my bathroom, and my stool is cloudy when passed and is extremely soft, crumbly, yet is not exactly diarrhea and does not hurt my anal region as diarrhea would, and the painful desire to expel my bowels does not return after it is passed. There is also a fever. I am not certain of how to check for swollen lymph nodes, and a doctor never checked for them. I originally thought I was having cardiac problems. These symptoms I am experiencing interfere with my quality of living. I have had breathing difficulties (in which I have had to breathe heavy) and chest pressure, and there was simply nothing determined to be wrong with me. My muscles in my shoulders have a lot of pressure and pain, that I just wish could lift off of me. I sometimes have a very weird feeling in my chest which cannot be localized (but it doesn't seem to be my lungs) and I feel I must lie in bed, and I suffer tremendously. This weird feeling makes me experience the need to cough. I am very weak, sometimes fatigued, and a little dizzy. There can occasionally be pain in my legs as well, and sometimes pressure on the upper left side of my stomach. Is this my spleen, or just my stomach? My pains are NOT sharp. My stomach rumbles and my throat gurgles often. I have had a headache, and generally just don't feel right. I have gone to my family doctor as well, and again, there was nothing perceivably wrong with me. I am profoundly unnerved when they dismiss me, hoping my age or gender is not a factor. This is certainly NOT stress, although I have been sent home, with medical professionals claiming it was probably stress. The only stress I have is caused by these unbearable symptoms and the uncertainty of my medical condition. Often, a symptom predominates all others. I was a bit dehydrated when I went to Emergency, but all they told me was to increase fluid intake. I have an irregular heartbeat, but this runs in my family and I've had it since birth. I don't know how much more I can take. This condition went away for about a week (or at least the symptoms were not present), and has returned once again. Is it serious, and what am I supposed to do? This condition is seriously destroying my life. I fall asleep with these symptoms, and even have them upon waking, although previously they were more intermittent. I am young and I just want to live! I am tired of fighting this alone. I just wish I could be diagnosed with something (non-serious, of course) just to put my mind at ease, and so my symptoms could be alleviated with medication and the disorder itself would no longer be there to interfere with my quality of living, because there is definitely something wrong. I want peace of mind, and I sincerely want my health to return to its optimal condition. I am fearful of simply being dismissed with nothing, because I just can't endure having to live like this and do not want to fight it on my own any longer, not even knowing what it is. I have a terrible fear of death. I just want to live normally, without health concerns. Please sympathize and help me, or else I just won't know what to do. This is the scariest thing I have ever had to face, and I just want to be completely cured. Please, are there any suggestions as to what this could be, and do you think it's serious, like leukemia? This is not asthma or pneumonia or stress. I was given Z-pack antibiotics for the possibility of infection by the Redicare clinic where I live. I vomited and had pouring, intense diarrhea, which was all over my clothes, the bed, and the floor. I do not think that this was due to my illness, but I drank water to clear it up. I never had these symptoms with my condition before, so the doctor told me to quit taking the medication. These are supposedly the side effects for some people, and not due to an overdose. I need a CAT scan and echocardiogram ordered by my family doctor on Tuesday. So I have a question for you: if I have already had blood work, an EKG, a urine sample, and chest X-rays, which were negative for any sort of condition, would the CAT scan and echocardiogram detect EVERYTHING? I will address leukemia with my family doctor, and maybe she will want more tests done. Do you think it's leukemia? I have gone almost a month without treatment for it, and the condition is still here, and I am scared on behalf of my prolonged lack of treatment. Will I survive, go into remission, without the possibility of recurrence or is my prognosis most likely to be poor, assuming I have leukemia? Please provide helpful and very knowledgable responses.
