My headache came on suddenly and felt like someone drilling into the back of my skull. Since then that pain has gone but I have had a constant headache. The pain is not touched by drugs, have tried ibruprofen and doctor prescribed diclofenac. A few days ago my left arm started to go numb and this now happens quite often. I sleep for between 7-8 hours a night and sleep reasonably well however I have general feeling of being unwell and have no energy and am tired all the time. I usually get woken by my alarm but this morning my headache woke me. I drink well, not alcohol, I eat reasonably healthily and am usually in good health. I am finding it difficult to concentrate and forget things and make silly mistakes, I have put this down to being tired all the time. I suffer from migraines and this is not the same type of pain. Has anybody had these symptoms and if so what did they turn out to be. Thanks
