This is my first post here as I'm using this website as a last resource - I've been to every doctor I possibly could and they find nothing but my symptoms do not subside.
I'm a 24 year old female, healthy (or am I), don't drink or smoke, don't take any medications and don't have any previous disease record (except for pneumonia when I was 6) or surgery history (except for wisdom teeth removal in August under local anesthesia).
Since I don't know what relates to what, I'll start from the very beginning:
Since the beginning of this year I have been getting a LOT of yellow mucus on my throat, which I managed to spit out when coughing. I went to an otolaryngologist, they made a CT of my sinuses (which were clear) and gave me anti-allergens for the mucus - which didn't help, but it wasn't bothering me that much so I let it go.
In September after coming back from a trip, I felt super sick, threw up and had diarrhea for over a week - which I did go to the doctor for and they said it could be a viral infection or food poisoning. I did a feces test and it came back clear, so they gave me no medication. Symptoms subsided after 2 weeks.
Since then I have been getting sick on and off (1 week I'm fine, the next I feel ran down, dizzy, stuffed nose, throat hurting. etc). I got 2 episodes of mild fever (37.5 degrees), but other than that I didn't get any. Then I got a super weird pain under my right shoulder blade which I thought was a pinched nerve (and this particular pain did go away after a few days), but my chest/upper back started giving me sharp pains randomly throughout my torso area and it sometimes hurts more when I breathe in.
I returned to the doctor and they said I had tracheitis (which I find unlikely since it's pretty rare and my voice was normal) and tonsillitis so they put me on antibiotics (10 days) and anti-inflammatory (3 days). During that time I felt worse and had multiple panic attacks (which I recognize I struggle with, but it had never been that bad) which took me to the ER and got sent back home with no diagnosis again and again.
Since I didn't feel better at all after the antibiotics, I insisted and visited more doctors (general, cardiologist and endocrinologist) and made a full exam (blood tests, x ray and EKG, which all came back normal), they all said I'm fine and shouldn't worry.
I then got a sore throat again and started producing more mucus (yellow), my nose is stuffy, I get shortness of breath (like I'm not breathing enough) and I'm still getting back and chest pain (the cardiologist assured it was not my lungs, even though I do not think it's muscle related - pain medication doesn't help and it feels a lot like the pain I felt when I had pneumonia), my ears feel clogged, I'm getting easily light-headed and with tingling arms and legs (this part might be anxiety, for it comes and goes) and started coughing like hell.
I understand I do have bad anxiety which may lead me to think I have a more serious condition than it actually is, but since my symptoms don't ever go away and may be getting progressively worse I don't think I could be THAT paranoid to make them all up for this long. I believe that we can tell when our bodies are not working properly, and mine definitely isn't.
I needed some help to figure out what other questions I could possibly bring up to a new doctor, what exams I should ask for and which doctor should I try to attend. It has crossed my mind it could be a lung clot, bronchitis, allergies, sinus infection... I don't even know at this point, but my other doctors assured me it's nothing serious based on the exams I took.
Sorry for the long post and hope I can get some help!
