I haven't had a flu shot in 4 years. The pharmacy I work at gives them free to employees so I figured I would get one this year. 2 hours after I came home from work I started having chills..so violent my teeth were chattering. Then my temp went up to 101.1 and my stomach felt as though it had a huge knot inside. It was so painful. I had chills for about 5 hours and then fell asleep after taking motrin, pepto and my lunesta. Today I am a little better but have that very tired flu sleepiness and have spent most of the day in bed actually sleeping...which I never seem to be able to during the day. I also now have the flu headache too. It seems as though whenever I try and do the right thing for myself I end up worse off...this will take me probably a week to recover from. Anyone else ever have this type of reaction?
