Talk to your doctor before adding any new medications to your existing regimen. Commonly recommended over-the-counter drugs include anti-inflammatories like ibuprofen, naproxen, and aspirin. Acetaminophen is helpful in providing added relief for the pain. Take the medications exactly as prescribed and talk to your doctor if you experience any side effects. Do not continue to take over-the-counter medications with prescription strength medications, unless your doctor specifically tells you to do so. Combining over-the-counter drugs with prescribed pain medications, anti-inflammatory agents, and muscle relaxers can be dangerous. Allow your body the time it needs to heal by getting enough rest while you pursue proper care. Appropriate care will likely include resting in short segments, like 30 minutes at a time, then walking or doing some light movements as recommended by your doctor and physical therapist. Avoid activities that can aggravate your condition, especially bending over and lifting and any twisting type of movement. Move slowly, and stop any activity if you feel pain. Pursue physical therapy that will include specific types of exercise to improve your condition. Initially the painful area will likely be swollen and inflamed. Applying ice, instead of heat, can help to reduce swelling and inflammation, and relieve the pain. Apply ice to the area for five minutes every hour. By the third or fourth hour, you should notice some relief. Continue to use the ice on the area of the bulging disc first, then you may also apply ice to any other affected areas, like painful nerves down your leg. Follow your doctor or therapist’s advice on how long, and how often, to continue the ice applications. Using applications of heat can be soothing to tight and sore muscles, and improve blood flow to the area. Improved blood flow means more oxygen to the muscles, and nutrients to the damaged disc. Talk to your doctor or physical therapist to determine the proper rotation of hot and cold that is best suited to your condition.
