Seek professional help from your doctor immediately if you feel any numbness or tingling in your groin or legs, if you lose control of your bladder or bowels, or if your walk is affected. You should also see your doctor if you are unsure of the cause of your back pain or if it is getting worse.  You will need further evaluation if you develop a fever or any new symptoms. Schedule an appointment. Be able to describe the exact nature of your back pain, how frequently your back hurts, what activities have become unbearable due to back pain, and any additional information that your physician might find useful. Your doctor will prescribe NSAIDs for general back pain, but can prescribe stronger medications if the pain becomes unbearable. Depending on the severity of the back pain, a doctor may suggest a steroid injection. Some people get relief for months or years when a steroid is injected into areas of the spine that suffer from extreme inflammation. Chiropractic professionals are dedicated to the non-surgical treatment of musculoskeletal conditions. Generally, they focus on your spine and the surrounding areas. Chiropractors use manual (hands-on) treatment to focus on lower back pain and herniated disc issues. This trained professional will prescribe necessary exercises much like a doctor prescribes medication. Physical therapists will teach you how to stretch and strengthen your back muscles. They'll also help you prevent unnecessary strain. Egoscue practitioners specialize in posture therapy. He'll focus on your back pain and identify any posture problems you may be having. He'll examine the way you walk, sit, and sleep. Afterwards, he'll outline a series of exercises that will help reduce pressure and tension in your back. The two best massages for lower back pain specifically are a quadratus lumborum (QL) muscle massage and a gluteus medius massage.  The QL massage focuses on the connection between your ribs and your pelvis - an area that is normally a source of lower back pain. This  area becomes strained when your lower back remains mobile while your upper body sits still or when you sit slumped in a chair. Your therapist can stretch and massage this area with a QL massage.  The gluteus medius massage works wonders in tandem with the QL massage. When the area between your ribs and pelvis becomes strained, it immediately causes strain in your upper buttocks region as well. A practitioner will insert thin needles into precise points throughout your body. Most acupuncturists argue that their needles stimulate the production of endorphins, serotonin, and acetylcholine. These are powerful painkilling chemicals naturally produced in your body. While the medical community is still out on the exact scientific effects of acupuncture, on-going clinical trials are hopeful. Certainly, there is a lot of anecdotal evidence (by patients) to support acupuncture's effectiveness. A Transcutaneous Electrical Nerve Stimulator (TENS) unit may be used as a treatment option to help block severe nerve pain. This is not a cure. It is merely a pain management technique. It essentially blocks pain signals to the brain, so you don't notice your back pain as much or at all. Only consider this technique after consulting your doctor and if all other methods have failed.

The unit rate is a special type of ratio in which the two separate measurements are compared and expressed as a quantity of one.  A "ratio" is any comparison of two numerical measurements. Each measurement is called a "term." A "rate" is a ratio in which the two terms are measured in different units. All rates are ratios, but not all rations are rates. A "unit rate" is a rate in which the second term equals "1." When calculating a unit rate, you need to determine how much of the first term exists for every one unit of the second term. The problem must have two terms, and you must be asked to determine how much of one term exists per unit of the other term.  Common examples include: speed (miles/kilometers per hour), unit price (cost per item), and wage (earnings per hour/week).  If you aren't sure about whether or not you're being asked for the unit rate, look for the word "per" somewhere in the description. Some unit rate problems won't include "per," but many do.  Example: A certain bakery can bake 40 loaves of bread in an 8 hour work day. How many loaves of bread can that same bakery make in one hour? In other words, how many loaves of bread are typically baked per hour? The first term in the problem—the amount you are trying to calculate per unit—will become the numerator (top number). The second term—the unit—will become the denominator (bottom number).  Example: You must calculate loaves of bread per unit of time (in this case, the unit of time is an hour). The total loaves of bread will become the numerator, and the total hours will become the denominator, giving you: 40 loaves / 8 hours To find the unit rate, simply solve the newly written division problem. Doing so will reduce the denominator to "1."  Example: Divide the total number of loaves by the total number of hours: 40 loaves / 8 hours = 5 loaves/hours You should now have your final answer ready.  Make sure that you include both units in your answer. You can either separate the units with the fraction sign (/) or with the word "per."  Example: This bakery can bake 5 loaves/hour. Alternatively, you could write, "This bakery can bake 5 loaves per hour.”

Leaving dirt or other particles on the wood can keep it from properly absorbing the paint, primer, and sealant. Clean the wood before applying sealant by wiping it down with a damp cloth. You can use a tack cloth to pick up any remaining dirt. Tack cloths are gauze-like materials treated with a sticky substance and can be purchased at any home improvement store. Brush a thin coat of glossy acrylic medium sealant onto the wood using a dampened sponge or paintbrush. Allow the sealant to dry, and then apply another coat to the wood. Lightly sand the wood after the second coat of sealant has dried to remove any excess sealant and then wipe it down again with a wet cloth and tack cloth.  Use a sponge for wood surfaces with grooves and curves and a paintbrush for flat surfaces.  The sandpaper should be around a 220 grit. Using primer provides a surface to which paint can adhere by allowing the wooden surface to regain surface tooth (ridges and valleys).  An acrylic gesso is probably your best option for using primers.  You will only need to apply one coat of a high quality primer, lower quality ones might require a second coat. In order to maximize paint adhesion, you’ll need to allow the primer time to dry. This could take several hours. Once the primer is dry to the touch, you can start applying your paint.
