If you have a concussion can you take pain killers?

Yes, sometimes post-concussion your physician will prescribe you painkillers to alleviate pain caused by headaches, or other injuries obtained during accident which caused concussion. However, it is important to seek professional help including but not limited to a CT Scan in order to ensure that particular pharmaceuticals are safe for your specific condition, as concussions often have unseen repercussions that need to be carefully examined by a Doctor before beginning any new medication, or even continuing old medications.
