I have had a dry cough for several months now. It feels like a tickle (as if I have inhaled salt). Occasionally, when I'm in the shower and have either very cold or very hot water hit my chest, it almost takes my breath away. The cough is non-productive (for the most part). I sleep soundly and breath clearly through my nose. My husband says I don't cough at all during the night.
In addition, my heart beats very fast when I get angry/excited or over exert myself (ie - lifting one of the kids to put them on the trampoline or play yard). I can walk several miles a day and it does not make me cough or lose my breath so I'm perplexed by this.
The only change in my life during these last few months is that I have cut out a lot of carbs. (not all) and started eating more protein, but not food high in fat (eggs, salad, nuts, meat). As a result, I have lost quite a bit of weight.
Not sure if the two are related but feedback on either or both would be appreciated.
