I've been on Betaseron for almost 3 years. The flu-like side effects are long gone for me. I believe they will get better for you, if you can just hang in there a little while longer.

My Beta shots also burn. They especially hurt when my husband gives them to me in the areas I can't reach (butt and arms). I think it's because I'm not in control, but they sure hurt! He also hates to do them.

Sometimes the ones I give myself hurt, too. I'm still having problems with big red spots and bruises when I do my upper abdomen. I'm also having problems sitting, and that butt shot was several days ago.

Having said all that, perhaps you should talk to your neuro about the problems you're having. The sweating and light-headedness are not normal, I would think.

Good luck to you!
