acute pain,

severe pain, as may follow surgery or trauma or accompany myocardial infarction or other conditions and diseases. Acute pain occurring in the first 24 to 48 hours after surgery is often difficult to relieve, even with drugs. Some studies show that patients over 50 years of age need less analgesia to relieve acute pain than do younger patients. Another study indicates that 23% of surgical patients, except for orthopedic patients, do not require analgesia. Acute pain in individuals with orthopedic problems originates from the periosteum, the joint surfaces, and the arterial walls. Muscle pain associated with bone surgery results from muscle ischemia rather than muscle tension. Acute abdominal pain often causes the individual to lie on one side and draw up the legs in the fetal position. Compare chronic pain. See also pain, pain intervention, pain mechanism.

Q. What's the difference between clinical depression that needs treating, and just regularly being depressed? I'm often depressed, and i just wondered what the difference is between just being depressed, and clinical? At what point does depression become depression?

A. It depends on the duration of the episodes, the frequency and severity. Even psychiatrists have trouble to pinpoint it. They often disagree on the “borderly” cases, here is some info on the diagnose of depression:

Q. Uncomfortable in my left-lower abdomen. But it is not acute or dull pain at all. I'm starting to feel uncomfortable in my lower-left abdomen. I roughly guess it started summer in 2008. Certainly, it's not acute or even dull pain at all. But it makes me very uncomfortable when I sit on the chair. I can feel it by sitting on the chair. Such uncomfortableness seems to reside in somewhere between my left leg and abdomen. It is under my navel, and to the left, extending to the my left flank. Once again, I can sense it by touching something developing (With my fingers, I gently pressed that area and, I realized that there's a difference between pressing on the lower-left abdomen and the lower-right abdomen.) But it is not something swollen, and not a hard thing. I've never had the caecum removed. I'm 40 years old, East asian. I quitted smoking in early 90's. In Octocber, 2008 I found my blood pressure pretty good (I can't remember it, though). My life is quite sedentary (I'm a graduate student.) I guess I spend most of my daily time on the chair. Thanks for any opinion in advance.

A. hi '''i do have the same thing all what i do is keep it higher than my hart and after a lettel time it well come back to normal and i advice you to go see a d'r when you have the rhit time for it.......and happy holly day and happy 2009..lolo21

Q. What Causes Acute Appendicitis? I've heard that appendicitis is a very common situation. What causes it to happen? Is there a way to avoid it?

A. Appendicitis is caused by an infection of the appendix, usually from bacterias that are already located in the abdomen. It is not a situation that can be avoided and can occur in a high prevalence in the population.
