History Of Chest Infections. Taken Antibiotics For Lung Blockage. Increased Heart Beat Now, Difficulty Breathing

Hi

I'm away in the UK at the moment from Australia. I have a history of getting chest infections, before I went away I had a cold and it moved to my chest although not bronchitis but just a dry cough that caused much pain to my ribs/chest area. The doctor diagnosed me as having costochondritis, before this i got a chest xray just to make sure it wasnt anything else, the Dr concluded my left lung had a bit of blockage but obviously wasnt too worried so Put me on Amoxycillin to get rid of the cough coz I was going away so soon...I'd usually try and fight it myself.

So I've been in the UK for 3 days now, finished my antibiotics 2 days ago and yesterday something weird happened. I had a coffee at a cafe and all of a sudden my heart starting going crazy. I know I may be caffeine sensitive coz this has happened before, but it made me go into a frenzy. Prior to having the coffee I did have a bit of a cough that I had woken up with. apparently the pollen is high in the UK and the people i am staying with think its that. Im not convinced though as It's like a throat tickle, non productive but made quite a loud rattle when I did cough. Makes me feel like I couldn't breathe properly and is quite distressing as I feel like my lungs are just going to close up.

Then after I ate my lunch I started getting really really bad indigestion, so chronic it was burning my chest and when Id burp it's bring a bit of relief but not much.

In the car on the way home my chest started tightening and feeling sore (something I am used to I get chest pain quite a bit) as well as my heart beating out of control. I couldnt stop the tickle cough either, I was coughing quite frequently. I felt so unwell I almost considered going to the ER. This scares me as I am a pretty healthy 21 year old female who doesn't drink much, non smoker, and exercises regularly when I'm not sick.

I calmed down a little, but then last night at dinner I started feeling extremely nauseous and shaky. I couldnt focus on anything and was really out of it. still felt really out of breath. I ordered dinner but could barely manage two mouthfuls. Again wanted to go to the ER.

When I Came home I had really loose stools and went to bed feeling quite unwell, woke up quite a few times in the night. I have woken up this morning with a sore stomach, that's another thing I wake up feeling quite unwell every morning like my stomach is line of burning, as well as short of breath again.

I am at the end... I am young and want to think I'm healthy but just don't know what's wrong. I really am trying to enjoy myself but can't and just want to go home. Sorry it is so long I just wanted to give you a full list.

I have another 4 weeks abroad and am worried something bad is going to happen to me! Please please help me.
