2 years ago I started having wheezing fits along with difficulty breathing and coughing every time I laughed, as well as once or twice a week when I go to bed. they usually last around 3 or 4 hours. I am not sure if it was just an allergic reaction or if I developed asthma. these symptoms would show even though I clean my apartment and my bed sheets regularly since I am allergic to mold and dust mite. last month I found a small patch of mold in the bathroom and cleaned it all away with a special cleaner, but despite by best effort I still have these symptoms as described.

5 days ago I went to my GP and explained to him basically what I wrote above, he said my symptoms sound like asthma but he was not 100% sure. he prescriped a belcometasone inhaler to use for 2 months two puffs a day and said to come back after that.

is this drug dangerous if used by someone who does not have asthma? will I have withdrawal effects when I stop taking it? I've read on the internet that it has several bad side effects like muscle cramps, thrush, tight chest, headaches...the list goes on, I already have a mild headache.

should I get a second opinion before I keep using it? I haven't been diagnosed with asthma before, and the doctor seemed quick to prescripe this inhaler.
