Fibromyalgia is a chronic disorder characterized by widespread muscle pain, fatigue and multiple tender points.  It can interfere with your ability to carry on normal daily activities. Like arthritis, fibromyalgia is considered a rheumatic condition. Unlike arthritis, however, fibromyalgia does not cause inflammation or destruction of the joints.   Treatment for fibromyalgia - drink Goji. This is a juice that is made from a berry.  This juice has helped many cancer patients, people who suffers from fibromyaligia, severe chronic pain, high blood pressure, memory loss, poor vision, menopausal symptoms, diabetes, headaches, liver and kidney problems.  It also increases yorur senergy and strength, diabetes and many more diseases.  Here is a testomony from someone who suffers from fibromyalgia.  "I suffer from fibromyalgia, rheumatic arthritis of the spine, chronic fatigue syndrome, irritable bowel syndrome and narcolepsy. I began drinking goji juice just three weeks ago.  In the last 2 weeks I have no experienced any seizures, spasms or tremors of the hands, legs or arms, and I have had no irritable bowel syndroms symptoms whatsoever!'\nMy sister had a very serious operation 6 weeks ago and had to remain in the hospital for 6 weeks to heal.  She was having very severe headaches to the point she just wanted to die because they were so bad.  I took her a case of goji to drink and she noticed later that night her severe headaches were gone.  All of the medication she was given couldn't stop the pain.  My sister couldn't thank me enough. She took 2 ounces of goji  twice a day.  She is now a goji advocate.  The recommended does for a fibromyalgia suffer is 2 ounces of high-quality goji juice 2 - 3 time per day.  Hope this helps.

Ergonomics is the study and practial functions of how we do things.  Our bodies when at rest have a general position. Example: At rest your arm, hand and fingers rest in the most natural position where ther is no stress or resistance, strain to it.  Ergonomics study began in the work place as more and more people were getting hurt on the job. The study intailed finding new ways to do the same job but with less stress and strain to the body.  Thus if there is less strain to the body, there is a less chance of getting injured.  Since the early'70's' studies  have not only been introduced into the work place, but is now being used all over.  When you go to buy a car or purchase furniture, the manufacturer has considered the body at rest into their design.  This practice can be found in almost every thing manufactured today.  Lets face it, we all have enough stress and strain in our lives, why should the things we use to make life more enjoyable and easier add addition strain and stress to our already overworked bodies.

Physical stress.\n\nThe first commercial jet airliner (the British-made Comet) had some accidents that were traced to the larger square/rectangular windows that were used...this forced a redesign - which other manufacturers copied for safety reasons.

Make sure you're fretting in the middle.  Also, there could be a small burr in the neck of your guitar, or even a problem with the string.

OK that might be me, lol.I will change my profile!!!! I have fibromyalgia. It is a illness reconized by the arthritis foundation. I will change my profile and put the whole name!!!\n\nWow, I am glad I saw this. Really. Thank you. I am trying to get ppl better informed. I know there are many that are sick and do not know what is wrong!!! Yesterday was National Fibromyalgia Day!!! \n\n\nA lot of ppl with it call it FMS. I do not have false memory sydrome, never heard of that. Sorry I just assume more ppl know about it. That is wrong of me. Their are so many illnesses. \n\nHere is a bit what it is: I have tons of links. Basically I have all kinds of problems. Some are sicker then me and some better. But I have daily pain, fatigue and many problems that never go away. I often feel like I have the flu. \n\nFibromyalgia\nAdapted from these Arthritis Foundation publications: Fibromyalgia brochure, Guide to Good Living with Fibromyalgia and Good Living with Fibromyalgia Workbook.  \n\nWhat Is It?\n\nFibromyalgia (fye-bro-my-AL-gee-ah) is an arthritis-related condition that is characterized by  generalized muscular pain and fatigue. The term "fibromyalgia" means pain in the muscles, ligaments and tendons. This condition is referred to as a "syndrome" because it's a set of signs and symptoms that occur together.\n\nFibromyalgia is especially confusing and often misunderstood condition. Because its symptoms are quite common and laboratory  tests are generally normal, people with fibromyalgia were once told that their condition was "all in their head." However, medical studies have proven that fibromyalgia does indeed exist, and it is estimated to affect about 2 percent of the U.S. population today.\n\nIn 1990, the American College of Rheumatology, the official body of doctors who treat arthritis and related conditions, finally legitimized fibromyalgia in the medical community by presenting its criteria for diagnosing it. It is diagnosed when the you display the following symptoms:\n\nA history of widespread pain (pain on both sides of the body and above and below the waist) that is present for at least three months\n\nPain in at least 11 of 18 tender-point sites.

Just try to de-stress and be sure you are getting enough sleep.  It sounds like you're irritable from being tired or frazzled.

Unit of force or force over area.\n\nkg-m-sec SI unit of force is the Newton (kg-m/sec^2).  Force over area is Newton/m^2 where the area is the cross-sectional area of the piece being broken.\n\nFatigue implies a wearing down (a fatiguing) of the structure (crystalline, molecular) of the piece tested until it breaks.  So time must also be folded into the measure of fatigue.  For this, mean time to failure (MTTF) is often used.  This is found by taken a number of test pieces, stressing them repeatedly, and noting when they fail.  The average time (in sec for SI) is the MTTF.

If you mouse a lot or have other repetitive motions, this is a sign that your muscles and tendons may be overstrained.  Please see a doctor asap for medical treatment.  I waited too long and....OUCH!

Check in with the doctor first to make sure you haven't worn down the tissue too much. It's probably just a stress injury, but those are some of the most annoying ones. Probably the reason the pain subsides is it goes into a numb-like state, or you just stop noticing because you're in the zone. If this has been bothering you for awhile take at least two weeks off. If you can't do that, then maybe cut back on your mileage to a minimum. Then at least you aren't breaking the habit.

Some people are more sensitive to the changes of pressure in the atmosphere, and can experience headaches, stiff joints, and fatigue.

It could be bursitis, an inflammation of the bursae( a fluid filled protective sac that reduces friction in the joints). You may end up having to see your Dr. but, try Motrin and rest, ice (20 min) and 20 min later heat (no more then 20 min) several times a day. But if the pain persists see your doctor.

They are the stresses normal to a rectangular element of the item being analyzed for stress.  A good explanation can be found here.......\n\n\nhttp://acm.uva.es/p/v104/10429.html

If it really bothers you, see a doctor. Fatigue is a symptom of all kinds of conditions.  It could a be a thyroid problem, epstein barr, fibromyalgia, depression, etc.It could a be a million things or it could be nothing. The point is if it is impacting your life negatively, you should really see someone about it. You may actually have a condition, and it is probably treatable- then you can get on and enjoy your life.

It's hard to tell from your description, but it might be bursitis. Bursitis involves swelling of the bursa, which are little sacks that help muscles glide smoothly over bones without friction. When the bursa swell up, movement in that area can be painful.\n\nSee link below for more information.

Hi!\n\nYield point (or yield stress) is the stress at which a material starts being plastically deformed, which means that, once you reach the yield point, the deformation becomes permanent. \n\nPoint load is a force applied to a specific point and distributed load is a force distributed throughout the analyzed structure.
