Pyrigesic 650 contains paracetamol, which is a helpful pain reliever but may not fully ease movement-related pain, which is often due to muscle strain or inflammation. For temporary relief, try applying a warm compress or an ice pack to your lower back for 15 minutes. Avoid sudden movements and rest in a comfortable position, like lying on your back with a pillow under your knees. Since the paracetamol hasn't helped, please consult a doctor. They can safely evaluate your back and suggest appropriate options like generic anti-inflammatory medications.

Jaw pain in someone with your medical history can sometimes be a sign of a heart issue, such as angina, rather than a muscle problem. Your safest first step is to seek immediate medical evaluation to rule out any cardiac concerns. Regarding medication, please avoid pain relievers like ibuprofen or naproxen, as these can increase cardiovascular and blood pressure risks. While acetaminophen is a safer pain medication for patients with coronary artery disease and hypertension, you should not take any new medication until a healthcare professional has evaluated your jaw pain and confirmed it is safe to do so.

Taking too much paracetamol (found in Pyrigesic 650, Dolo, and Acemiz Plus) can strain your liver, and vomiting is a sign your body needs immediate care. The most important step right now is to go to the nearest emergency room immediately. Doctors have highly effective treatments, like an antidote called N-acetylcysteine, which works best when given early. Please bring the medicine packaging with you so the medical team knows exactly what was taken.
