Headache medication – why less may be more
Strange but (sadly) true: medicines you take for headache relief can cause headaches. The reason is the way the central nervous system (CNS) adjusts and self-regulates. If you use pain relief medication for a long time, your CNS lowers your pain threshold and you become more sensitive to pain. Your CNS does this to restore your original, ‘normal’ level of pain sensitivity. That is why stopping pain medication after long-term use may trigger an agonizing “rebound” (withdrawal) headache. Taking painkillers to treat that pain can catch you in an endless cycle of worsening pain and increasing medication use, ultimately resulting in medication overuse headache. The good news is: you can do something to stop it.
