Second hand smoke symptoms and conditions

Hi I am 31, have been put on prednisone for a pinched nerve in my shoulder blade. Iv taken two pills of 10 mil. For two days. one pill a day for two days. I'm stopping now. I feel so tired weak and unable to exercise. My chest is so heavy and heart flutters. I'm a smoker so it seems worse after a cigarette. I also have a few glasses of wine a day. I'm so frightened at these feelings. My tummy is now bigger in just that short of time. I really wish I knew all this first. Can any one tell me how long before I'm normal from the short usage. Please this really sucks and very scary. Also the smoking and alcohol how does it effect this? Please

It started as a cough... thought I had a cold but just cough continued until I lost my voice. I coughed so hard I thought it was something much more serious since my mother died of lung cancer. I have never smoked but got plenty of second-hand smoke. Doctor said it was allergy/asthma and prescribed Prednisone (7 day) and Advair. Prednisone is now gone but still have trouble with voice breaking up, some cough, and not leg cramps, stomach cramps and dizziness. I am on 250/50 and also prescribed and using Albuterol and Flonase. Thanks for this site and information. I will discontinue Advair and see the reaction. I am now not so worried. -Pamela-
