I just got my meningitis shot yesterday. Now tonight for the past several hours my head has been hurting..feels like my brain is swelling...which is what meningitis does I guess. My arm was hurting from where I got the shot so I took a motrin to "relieve" the pain and then after that my head started to hurt. It's been over 24 hours since I got the shot too. Is this just a headache from spending to much time watching tv or staring into a computer screen or should I possibly be concerned? Thanks
