For safety's sake: In general, I suggest you limit your use of OTC painkillers for aches and pains to once a week. And always try natural remedies first. When I have a headache, dehydration is usually the cause, so I drink a glass of water. If the pounding doesn't go away in 30 minutes, then I'll take medicine. For chronic muscle pain or arthritis, I recommend capsaicin cream, which depletes a neurotransmitter responsible for sending pain signals to the brain. Ginger, another option, has been shown to fight both inflammation and pain within 24 hours; try grating a half inch of ginger into a cup of tea for a soothing, refreshing drink. If pain persists, consult your doctor about other options to ease your discomfort.
