this flu is dragging on

I was diagnosed with flu b last tuesday (swine flu is flu a)
I was given relenza and told to rest, drink fluids, take ibuprofin and rinse with salt water (which I did)
I kept feeling progressively worse each day instead of better...the weird thing is that my fever had never gone past 100.

on sat, I went back to the dr and was told that as a complication, I had gotten a sinus infection and bronchitis and was given antibiotics and told to keep taking the relenza and ibuprofin also. today (monday) I still feel short of breath, weak and (at times) light headed, but I do feel better than I did....should I still be having symptoms after being on the meds for so long?

My mom told me I should go to the ER, but she overreacts to all medical issues.

I'm just sick of feeling like this and am wondering when it will all go away. it's already been 7 days.

thanks for reading.
