someone please help me :(

Hi everyone, my name is Sky and I am turning to the internet in hope of finding the answers several GPs are unable to give.

I'll start from the beginning...

I have always been active, my parents raised me on healthy foods and living life to the full. Playing outdoors, kicking the football, joining netball at school, roller skating weekly... We were never inside kids.

At the age of around 11/12, I started to develop a shortness of breath upon exertion. Rollerskating that I had participated in since 7 years old, suddenly started to become very strenuous. A few laps and I couldn't breathe accompanied with a general weakness feeling. It wasn't particularly overwhelming, I brushed it off as being unfit. I was young and not alarmed.

At around 14/15 I pushed myself when it came to joining football at school. The once dream of mine was crushed when it turned out I could no longer run at all. I continued to push myself and play for a total of 3 years, but I was always put on the backline and never had go :(

It was around the age of 15 my mother took me to the doctor, who completed no test, but immediately diagnosed me with Sport Induced Asthma. I had ventolin and the steroid puffer, neither of which ever relieved me.

After leaving school, with my two dreams crushed due to my breathing. I gave up any activity for at least a year.

At the age of 19, I decided to join a gym. I had never gained weight in this gap, I still ate well and always looked after myself. I have always been slim, but not thin.

At the gym. I could only ever walk and do light weights. Running, moving too fast, lifting... It would send me gasping for air within 10 seconds of exertion. Much worse than a few years earlier. The breathing struggles had significantly progressed. I continued to push myself, joined a Body Combat class, and ran out after 5 minutes close to fainting from lack of air and dramatically increased heart rate.

Trying to keep moderately active, at around the age of 21, sharp and quite severe at times, chest pain would start to present itself. I would wake up in the middle of the night with a heart "crunch" feeling, like those awful leg muscle cramps you get that leave you crying.

The chest pain started in my sleep, something I initailly wrote off as panic of not being able to breathe while laying down. For around 6 months, I had to try sleep upright, as laying down inhibited my breathing dramatically.

From around this same age, my legs would burn so badly (heat) while laying down, that I would have to wear pants every night so that my legs couldn't touch and get hotter. This still persists at the age of 24.

I have been tested for diabetes twice, both coming back negative. I have also been properly tested for asthma and this is also not present. Both recent results.

Now, at the age of 24, and for the past two years, symptoms are worse than ever. Bending down to pick something up will result in shortness of breath, a very hard and noticeable heart beat and feeling lightheaded.

I go to the gym regularly now. Two minutes on a stepping machine on light to medium will send my heart up to 175bpm.

At rest, I am puffed. Laying down I struggle to breathe, even just talking to someone.

The chest pain now is far more intense than it has been before. It is very intermittent and some days worse than others. I will be on the treadmil and I get sharp pains. Very pinpointed. If I push myself too much, I get pains down my left arm.

Chest pain in the future could be so dangerous for me, as it has been persistent for so long that I now ignore it. It doesn't phase me anymore as it has become normal.

I feel weak, breathless, and like it is all getting worse. I never feel at ease, even at rest.

My biggest concern is how bad I feel now just at rest. I feel like I'm suffocating.

I am 24, 163cm, 55kg, active, a healthy eater. I sleep 8 hours a night but if I do sleep 6 or less, my symptoms are much worse.

I have been to doctor after doctor, they all assume asthma.

I want to live life, I would give anything to run, I just want to fix this.

Someone, please help me. Doctors write me off because I am young.

Thank you xx
