Chronic pain syndrome – chronic pain starts with an acute injury or illness. If the pain of this injury or illness lasts longer than six months, it’s then considered chronic pain. Sometimes, chronic pain subsequently causes complications. These complications, in turn, can make the pain worse. A chronic pain syndrome is the combination of chronic pain and the secondary complications that are making the original pain worse. http://www.instituteforchronicpain.org/understanding-chronic-pain/what-is-chronic-pain/chronic-pain-syndrome

Diabetes – A group of diseases that result in too much sugar in the blood (high blood glucose). www.diabetes.org/

Diverticulitis – Diverticula are small, bulging pouches that can form in the lining of your digestive system. They are found most often in the lower part of the large intestine (colon). Diverticula are common, especially after age 40, and seldom cause problems. Sometimes, however, one or more of the pouches become inflamed or infected. That condition is known as diverticulitis (die-vur-tik-yoo-LIE-tis). Diverticulitis can cause severe abdominal pain, fever, nausea and a marked change in your bowel habits. http://www.mayoclinic.org/diseases-conditions/diverticulitis/basics/definition/con-20033495

Fibromyalgia is a musculoskeletal condition causing wide spread pain in the muscles and joints. It can cause one to experience “brain fog”. Brain fog impairs the ability to remember things and preform mental tasks. http://www.fmaware.org/about-fibromyalgia/symptoms/

Generalized anxiety disorder – It’s normal to feel anxious from time to time, especially if your life is stressful. However, excessive, ongoing anxiety and worry that interfere with day-to-day activities may be a sign of generalized anxiety disorder.

It’s possible to develop generalized anxiety disorder as a child or an adult. Generalized anxiety disorder has symptoms that are similar to panic disorder, obsessive-compulsive disorder and other types of anxiety, but they’re all different conditions.

Living with generalized anxiety disorder can be a long-term challenge. In many cases, it occurs along with other anxiety or mood disorders. In most cases, generalized anxiety disorder improves with medications or talk therapy (psychotherapy). Making lifestyle changes, learning coping skills and using relaxation techniques also can help. http://www.mayoclinic.org/diseases-conditions/generalized-anxiety-disorder/basics/definition/con-20024562

Interstitial cystitis is a chronic inflammation of the bladder. It causes the bladder lining to crack, bleed and become stiff, causing severe pain, urgency and frequency. Some people get ulcers in the bladder called Hunner’s ulcers. It is treated with diet, bladder distention, bladder installation, and medication. It is a debilitating disease with no definitive known cause and no cure. Read more here: http://www.ic-network.com/conditions/interstitial-cystitis/what-is-ic/

Irritable bowel syndrome – Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine (colon). Irritable bowel syndrome commonly causes cramping, abdominal pain, bloating, gas, diarrhea and constipation. IBS is a chronic condition that you will need to manage long term.

Migraines – A migraine can cause severe throbbing pain or a pulsing sensation, usually on just one side of the head. It’s often accompanied by nausea, vomiting, and extreme sensitivity to light and sound. Migraine attacks can cause significant pain for hours to days and can be so severe that the pain is disabling.

Pelvic floor dysfunction – a wide range of issues that occur when muscles of the pelvic floor are weak, tight, or there is an impairment of the sacroiliac joint, lower back, coccyx, or hip joints. Symptoms include pelvic pain, pressure, dyspareunia, incontinence, incomplete emptying, and gross organ protrusion.

PTSD – Posttraumatic stress disorder, or PTSD, is a serious potentially debilitating condition that can occur in people who have experienced or witnessed a natural disaster, serious accident, terrorist incident, sudden death of a loved one, war, violent personal assault such as rape, or other life-threatening events. Research has recently shown that PTSD among military personnel may be a physical brain injury, specifically of damaged tissue, caused by blasts during combat.

Sleep apnea – Obstructive sleep apnea is a common and serious sleep disorder that causes you to stop breathing during sleep. The airway repeatedly becomes blocked, limiting the amount of air that reaches your lungs. When this happens, you may snore loudly or making choking noises as you try to breathe. Your brain and body becomes oxygen deprived and you may wake up. This may happen a few times a night, or in more severe cases, several hundred times a night. http://www.sleepeducation.org/essentials-in-sleep/sleep-apnea

TMJ – The temporomandibular (tem-puh-roe-mun-DIB-u-lur) joint (TMJ) acts like a sliding hinge, connecting your jawbone to your skull. You have one joint on each side of your jaw. TMJ disorders — a type of temporomandibular disorder or TMD — can cause pain in your jaw joint and in the muscles that control jaw movement. The exact cause of a person’s TMJ disorder is often difficult to determine. Your pain may be due to a combination of factors, such as genetics, arthritis or jaw injury. Some people who have jaw pain also tend to clench or grind their teeth, although many people habitually clench or grind their teeth and never develop TMJ disorders. In most cases, the pain and discomfort associated with TMJ disorders is temporary and can be relieved with self-managed care or nonsurgical treatments. Surgery is typically a last resort after conservative measures have failed, but some people with TMJ disorders may benefit from surgical treatments. http://www.mayoclinic.org/diseases-conditions/tmj/home/ovc-20209398
