PredniSONE and wich

I went to the doctor for trouble breathing. I also wanted to take a physical cause I have never taken one. So he just checked me and prescribed me prednisone 10mg 1pill every antibiotics, and an Inhaler.

The side effect was swollen face and neck within the week of taking it. I would take one a day or sometimes I wouldnt take it and vise versa. But It was supposed to be for 5 day wich would be 10 pills and since. The doctor said yeah keep taking it. So this past week has been 6 more.

16pills in total through a period of three weeks and what I feel is
Pain in my left shoulder. Like muscle pain. My breathing problem once in a while. When I dont have anxiety. My face is not swollen, cause when it did get swollen I would feel it.
Well the doctor said after my X-ray exam that I had bronchitis and previous imflammatory disease. but still I dont know what was the problem in the first place.

For this amount of prednisone how Much effect is it going to do?

Because its been 2 days that I dont take it.
