GAWD I HOPE SO. I'm actually feeling fine now. I just let the fever ravage me for the first day, then when the fever settled down, I took some ibuprofen, and I've been fine since.
After the first day of misery, I took ibuprofen and I was feeling much better. Now my arm is still a tiny bit sore, but I feel 100% again. Worst fever of my life though.
