Alright so I recieved my first HPV vaccine about 4-5 hours ago and ever since then I have a headache. In the side affects it does say you may experience a headache but the headache Im experiencing is like a migraine it feels like my head is under pressure and and has a sharp pain in many places. I took 2 paracetamol tablets 5 mins ago and Im praying for it to go away. I also feel slightly neauseous. I didnt really want to get the vaccine but I did anyway and I really feel bad for getting it. Im 14 years old aswell.
