allergy shots, pills and weight gain?

Like above. Has any one with allergies experienced weight gain? I suffer from sesonal allergies plus cats, dogs, rabbits. I was on the shots weekly for 6m plus pills and when I started thinking about I have gained some weight during the shots. I wolud never put this together, but I've heard somebody talking about how much more she is eating when she is on allergy pills.

I have been on allergy shots for while year of weekly shots then 2 years every other week still on them every other week for another year.. I also have to take prescription allergy pills and steroid nasal spray.. I haven't notice weight gain if I did it's because of not eating right.. But what I am noticing it's next to impossible to lose weight.. I have been watching what I eat following the rules that Humber wants us to do, tracking my steps I have increased my steps from 5000 to 6000 steps a day to 12 000 to 15 000 haven't lost that much my scale says around 12 to 15 lbs not much for the last few months.. So I am not sure if it related to the treatment or not but this is what I am experiencing.
