Ugh. I hate to be the bearer of bad news, but I had them when I was in my 20's and it was one of the worst experiences of my life. Part of that though was that I was living alone and I only had one friend that was brave enough to stop by during the lunch hour to make sure I was still alive lol
If you've got a partner and/or other family/friends that are willing to help cook, keep the house up and take care of the kids so that you can just lie in bed it'll be much easier!

I think I was out of work for about 5 days.
I had pretty high fevers and am anti-meds so I just kinda sucked it up.
Make sure you have lavender essential oil on hand and calamine lotion, a combo application of those works great for the itching.
Good Luck!!!
