asthma
"I started taking it about a year ago, It has reduced my need for an inhaler but recently I ran out and as I had been experiencing anxiety, I decided to see how I went without it. I immediately noticed a tight chest and wheeziness and I was not anxious at all, but I also noticed I started getting headaches and pins and needles. I then started taking them again and the headaches and pins and needles disappeared but I am curious as to whether they are linked."
