Well yesterday was my 18th birthday and I didn't drink much at all, but I had these stabbing pains in the left side of my brain more towards the back. They lasted all day and even now this morning they have come back in the same spot. Also my left ear hurts. Could it be something like a brain tumour? Please help. Thanks.
No, it could be just a reaction to alcohol if you don't usually drink. You can take one caffetin, or something like that and it will go away. It works for me. Try to sleep and drink plenty of water to expel it from your organism as fast as possible.
