I start to cough when my chest is exposed to cold air

[lmi71]

Some background on my coughing... In 2009 I got pregnant with my first child. 2 months into the pregnancy I started coughing. The coughing got so bad I would end up vomiting. Soon after I had trouble breathing. After seeing my doctor several times and having several breathing tests done all my test results were normal, so my doctor sent me to a Pulmonologist. His conclusion was that I had developed asthma and put me on several different medications assuring me they were all safe for the baby. After a month of not getting any better, he wanted to up all my meds and prescribed me several more. Being at my wits end, I went to see a Gastroenterologist thinking it could be a silent reflux and then to an ENT all to no avail - they both said they couldn't find anything wrong. So I went back to my original doctor who immediately had me stop everything the Pulmonologist gave me and told me I was going to have to try and deal with the cough. Long story short it ended up being my prenatal vitamin. I was allergic to the high dose of folic acid. After coughing and not being able to breathe for almost 6 months, as soon as I stopped taking the vitamins I stopped coughing. But I think I have lingering after effects from that episode, as every time my chest is exposed to cold air I start coughing. In the summer I have to keep my chest bundled up from the AC. In winter, I can go out in the cold and breathe in the cold air with no problem, but if my chest is exposed just a little bit I will start coughing. I have tolerated it since my doctor can't find anything wrong and I am getting frustrated. Does this sound like anything you have ever heard of and is it at all possible that the allergy I had to the folic acid somehow compromised my lungs and is to blame for my coughing now? As a side note, my daughter is a happy healthy 22 month old now. :-)

Hello and hope you are doing well.

Asthma is usually triggered by allergens. It's unlikely that folic acid could be causing the allergic cough. You may be sensitive to cold and dust mites this could be triggering the attacks. You could consult an allergy specialist to see if allergens are triggering the reaction.

Hope this helped and do keep us posted.

Thanks Tschock, :-)
But I rarely got sick as a kid or now as an adult. I never had asthma and I had bronchitis 2 or maybe 3 times in all my 40 years. I am not saying that folic acid is causing it now, but perhaps because it got so bad when it was happening and not diagnosed properly for so long that it somehow damaged my bronchial tubes, lungs, whatever. This is something new for me. I never had this coughing problem before I started the folic acid and If I became sensitive then I would imagine that it has something to do with the allergic reaction i had.
