I have been very sick this week. Started with a simple case of vaginitis. Was given antibiotics to which I reacted very badly causing a fully blown inflammation of the genital area which then went on to become what appears to be a first attack of hvs2 and was given valtrex valaciclovir for. I have been getting headaches ever since which are getting worse. The strange thing is that they start the moment I lay down. As I turn my head to the right the headache moves to the right. If I turn my head onto the left so does the headache. If I then get up it stays for quite a while but after an hour or so starts to fade. As soon as I lay down it starts again. What could this be?
