Sciatic pain can be caused by many conditions of the lower back and spine. Your doctor will know how to test you for these conditions. The types of tests and examinations your doctor chooses will depend on your symptoms and state of health, but may include both simple physical examinations, as well as imaging techniques such as an X-ray or MRI. Be as detailed as you can when describing your symptoms to your doctor, as this will help them determine which tests to perform. Common causes include: herniated or slipped disc, piriformis syndrome, spinal stenosis, or spondylolisthesis. Normally, sciatic pain dissipates after a few weeks. If your doctor determines that surgery is not needed, they may still recommend medications to provide relief from the pain while you recover from your sciatica. Typical choices include: Oral steroids, which provide powerful anti-inflammatory effects, reducing inflammation and irritation in the region surrounding the sciatic nerve. Muscle relaxants or narcotic pain medication to reduce pain. Steroid injections work much like oral steroid medications, temporarily reducing inflammation and irritation surrounding your sciatic nerve. Injections are more invasive than regular medication, but are also more effective. Your doctor may recommend steroid injections if your pain is sufficiently severe. Sciatic pain can be caused by a variety of factors and conditions, most of which do not require surgery to fix. When sciatic pain is due to discs or bones in the spine physically contacting and "pinching" the sciatic nerve, however, your doctor may recommend surgery to correct the problem. Two types of surgery are most common: For herniated discs (this is when the discs that cushion the important movements of the spine develop a weak area and the inner core pushes out), microdiscectomy may be performed. In this procedure, the piece of the herniated disc which is in contact with, and irritating, the nerve is removed. For lumbar spinal stenosis (narrowing of the discs of the spine causing them to "pinch" the nerve), lumbar laminectomy may be recommended. This is a more serious surgery in which the disc is reshaped to allow the nerve to rest comfortably once again. After your doctor has recommended medication, and potential surgical solutions for your sciatic pain, they may recommend that you begin working with a physical therapist. Your therapist will help you learn exercises and stretching routines to strengthen your core, and support your spine. Creating strength and stability in the lower spine is the first step to permanent relief from sciatic pain. Many sufferers of sciatica find that treatment by a chiropractor helps to relieve their pain. Although more research is required to confirm the effectiveness of chiropractic care, recent studies have shown promising results for many patients with sciatica. If traditional treatment methods have failed to alleviate your sciatic pain, talk to your doctor about less typical options. Here are some suggestions of alternative therapies to talk to your doctor about: Therapeutic massage to relieve tension and inflammation Yoga classes, to promote core strength and flexibility Cognitive behavioral therapy to teach strategies for pain management Acupuncture, or other traditional therapeutic methods

That old saying "you are what you eat" exists for a reason: it's important that you eat the correct proportions of quality foods to get the minerals, vitamins, protein, and healthy fats you need for muscle development. In particular, be sure to eat plenty of protein, which your body uses to rebuild muscle you've broken down in workouts. Try to eat some high protein food about 20 minutes before and again directly after a strength-training workout. The amount of calories you should take in per day varies by age, gender, and lifestyle. Drinking water will help to reduce your sense of hunger and also allow you to exercise longer and better. Your body is approximately water and it must continuously be replaced to make up for what is lost through breathing, sweat, urination, and other bodily functions. Teenagers should try to drink 8 to 10 glasses, or 2 liters of water per day. Adults should have between 2.2 and 3 liters of water every day. In order to improve your overall fitness level, you're going to need to get active more often, even if you're busy. That means you need to design a fitness plan for yourself. Physical trainers recommend that individuals take four to five days a week to work out. If you're looking to build up muscle, then you might spend three to four days for strength training, one day on cardio, and two days of your week "active resting," which refers to doing something light like yoga or walking. In order to have good results, it is of the utmost important that you have a routine and that you stick with it. It is important to have cardiovascular workouts incorporated into your routine in order to help reduce fat since fat lays on top of and can hide muscle. Your goals must be concrete and reasonable or else you may give up. If you never exercise currently and you want rock-hard thighs, you will need to start with routines that are less strenuous (like incorporating smaller weights, shorter cardio workouts, and fewer reps) and work your way up. Some specialists suggest that in one year's time, beginners can gain up to 10% of their total body weight or 2 lbs of muscle per month with dedicated training.
