I am 23 and noticed breathing issues a few years ago. I was in college at the time and didn't want to go to the doctor because I didn't have trouble breathing, I just didn't have as much breath as I thought I should have (and as I remembered having in High School).

After chest pains a few weeks ago, my worried and sweet wife convinced me to go to the doctor. After some pulmonary tests, EKG (to make sure the chest pains were not my heart) and X-rays (no heart swelling, thank goodness) the doctor said I had mild asthma and put me on Advair. It's been a week now, and if anything my chest hurts MORE. It's still not too bad, but I definitely don't feel any better.
I don't have major asthma attacks, but I do wake up sometimes with slight breathing issues and need to get a drink of water and cough a few times to go back to sleep. I also get a tight and painful chest (normally on the left side, but this morning on the right) sometimes.

What can I expect from the medicine and what’s the best way?

Thanks in advance!

Do call your doctor and mention all you are going thru, and don't get off the phone or leave the office until youo get answers to your questions.

Mal is right. Definitely call your doc. I would never come to a place like this for medical advice.

Your doctor may prescribe things for you to use against what seems to be mild asthma which may not be too good for you in the long run. The Buteyko method is proven, safe and very effective. The book Close Your Mouth and ABC to be asthma free are self help books to teach yourself the Buteykjo clinic method. They are available from Amazon.com: Online Shopping for Electronics, Apparel, Computers, Books, DVDs & more for USA and amazon.co.uk for UK and other countries. Patrick McKeown a renowned practitioner teaches many other natural clinic methods at his site Asthma Care Ireland- Featured on RTE and TV3, Buteyko Clinics and books It will be well worth your time.

as a nurse, a sufferer of asthma and a daughter who does too i would reiterate what some of the others have said and go back to your dr asap.the inhalers come in 2 main groups preventers eg becotide and relievers, eg salbutamol. i am in the uk so your inhalers will have different names so i cannot tell what you have been given. but you may need to use both types (or a combi)at least to begin with or need a stronger dose etc . also the relievers will give almost immediate relief to a tight chest, wheeziness etc whilst the preventers can take a week or 2 to reach theraputic levels and must be used as prescribed even if you feel well.
the Buteykjo method is worth looking into but do not stop any dr prescribed medication without seeking professional advice.
what i have told you is only based on my knowledge and experience and shouldnt substitute proper medical advise.slim
