Thank you, Charleyhorse. I'm really not even sure why he gave me the shot in the first place as I have not been having any trouble with my allergies/asthma recently. I've not been feeling well the lately, running a low grade fever for almost two months now, and an ear infection for over a month. Two rounds of antibiotics in the past month didn't help at all so I think he was running out of options and threw that shot in to see if it might help. He also gave me another scrip for an antihistimine I already tried once this month and it hadn't helped.
On the upside, it does seem to have gotten rid of my sinus headache. And my BG levels have actually gone down the last two days. So I am feeling better.
