Flexeril Pain Causes and Reviews


Pain is a signal in your nervous system that something may be wrong. It is an unpleasant feeling, such as a prick, tingle, sting, burn, or ache. Pain may be sharp or dull. It may come and go, or it may be constant. You may feel Pain in one area of your body, such as your back, abdomen, chest, pelvis, or you may feel Pain all over

Pain can be helpful in diagnosing a problem. If you never felt Pain, you might seriously hurt yourself without knowing it, or you might not realize you have a medical problem that needs treatment.

There are two types of Pain: acute and chronic. Acute Pain usually comes on suddenly, because of a disease, injury, or inflammation. It can often be diagnosed and treated. It usually goes away, though sometimes it can turn into chronic Pain. Chronic Pain lasts for a long time, and can cause severe problems.

Pain is not always curable, but there are many ways to treat it. Treatment depends on the cause and type of Pain. Pain relievers and other medicines, acupuncture, physical therapy, and sometimes surgery may be helpful.

anxiety, anger, and exhaustion
Mon, 18 Apr 2011
I was taking Flexeril after I was diagnosed with a rib contusion following heavy lifting. I am taking Lexapro, Adderall and Trazadone already for A.D.D. depression and sleep deprivation. The Flexeril made me extremely tired, irritable, so much so that after a 24 hour period, I was nearly suicidal, possibly homicidal. I threw the medication away after reoccuring this feeling several times.
