When thinking about how painkillers work, it helps to understand what is happening on the inside. You may see advertisements on television which refer to “targeted pain relief” that is fast-acting and will stop the pain in a specific area.
While taking something like paracetamol or ibuprofen, for example, helps with pain relief, the medicine hasn’t actually pinpointed where your pain is and gone directly to the source.
Medicine has to make its way around the body to find the source of inflammation and calm the effects of pain. For most people, it’s absolutely fine to let painkillers do what they have to, but for those with high blood pressure it is important to know what else the medicine may be doing in your body and why there could be risks.
