For about 3 weeks now I have been experiencing difficulty sufficiently breathing, especially at night. It's a sensation that I can only describe as a feeling of not being able to get enough air in my lungs' or 'a tightness in my chest/airways. It's still apparent during the day but worsens by night. I also have a dry cough accompanied by wheeziness when I inhale and I feel like I might need to phlegm but it hardly ever comes out. On the rare occasions that I do actually phlegm; it's mostly clear and rather sticky.
Moreover, last week I went to see my GP, he examined my chest with a stethoscope and failed to detect any signs of infection in fact; to my surprise he even said that my lungs sounded rather 'healthy'. He did however notice that my pulse was rapid and saw that I had previously come to the doctors with issues regarding anxiety and was very keen on pinning everything down to anxiety. I was quite skeptical of this but went home and tried to ignore the symptoms. A couple of days passed and the symptoms were still there and so I booked an appointment to see a specialist nurse.I explained my symptoms to the nurse and she then examined me with a stethoscope. She said that my chest sounded fine and there was no sign of infection. She then came to a conclusion that I might be suffering from gastroesophageal reflux disease (GERD) as I told her that I occasionally get heartburn. She prescribed me some omeprazole (a medication that controls the amount of acid produced in the stomach.)
I've been taking these every day for the past week but I'm just extremely dazzled and confused. How on earth could a stomach related issue effect my breathing? How was she so keen on pinning it down to acid reflux, even though I wasn't experiencing the main symptoms of it?? I'm just utterly confused! In my opinion I was experiencing asthma like symptoms but neither the doctor or nurse tested me for asthma. I just want some advice and closure on the subject as it's keeping me up at night and getting me worried.
additional information:
-I'm a 17 year old male.
-I used to smoke on occasions but I've completely stopped for about a month. (could the difficulty breathing be connected to quitting smoking?)
-I've had many lifestyle changes recently, for example I've had a change in diet, stopped consuming caffeine and have been doing a lot of exercise (but however have stopped since my symptoms arose)
Thanks you for reading, advice + your opinion would be much appreciated
