In a nutshell, an allergy can be defined as an abnormal reaction from an individual’s immune system normally against a harmless substance. Individuals with no allergies would not have a reaction to these substances, or allergens, but the body’s of those who do release certain chemicals and it is these that cause the allergy symptoms.
An allergy can range from such things as itchy eyes to rashes to runny nose and is so widespread that they can affect 25% of the population at some stage of their lives. People have to be aware though, that these symptoms can be caused by factors other than an allergy as well, and could well be from a disease instead. More or less anything can be classed as an allergen for an individual but the most common come from pollen, dust mites, pets, insects, industrial chemicals, certain medicines and some foods like eggs and milk.

Common Allergic Reactions
The immune system of an allergic person reacts by producing special kinds of antibodies called IgE when it thinks it is being “damaged” by an allergen, and these antibodies attack the invader. This procedure then causes other blood cells to discharge other chemicals, which together with the antibodies cause the allergic reaction symptoms.

Blood pressure is described as the pressure the force of blood applies to the artery walls as it flows through them. It is the pumping action of the heart that causes the blood to be under pressure. Normal blood pressure is an essential function in the workings of the body. Blood pressure is denoted by two numbers, 120/80 being an example (which happens to be considered an average blood pressure reading, by the way), with the first number being the systolic blood pressure, or the pressure when the heart is contracted while pumping the blood, and the second number is the diastolic blood pressure reading which is when the heart is at rest while filling with blood.
Naturally low pressure (usually thought of as lower than 90/60) doesn’t indicate any problems health wise. It could be normal for some people and indeed beneficial as it can lower incidences of stoke and coronary heart disease. It only becomes a problem if it is accompanied by symptoms such as fainting. This is normally caused by an underlying problem which would indicate that the blood pressure is not being regulated properly.

What to do in the case of Low Blood Pressure
If someone has constantly low blood pressure, then this could be classed as normal, however, if they have postural hypotension (blood pressure drops when standing up from a sitting position) or postprandial hypotension (blood pressure drops after eating), could mean there are underlying health problems. These could be taking drugs that are used to treat high blood pressure, illnesses that cause blood loss, diabetes, Addison’s disease (an adrenal gland disease), and early stages of pregnancy.
Treatment of low blood pressure normally depends on the underlying cause of the problem.

Whereas acute pain in an individual is a typical sensation that is usually triggered to alert them of a possible illness or injury, chronic pain differs in that it can last for weeks, even months or years. Although there could have been an initial trigger for this pain such as an infection or injury, or ongoing pain because of such things as cancer or arthritis, some people can suffer from chronic pain without any prior illness or injury.
Generally, chronic pain tends to affect older people and the complaints associated with this can include lower back pain, headaches, arthritis pain and cancer pain. There are some treatments that are prescribed for sufferers of the condition and these include medication, electrical stimulation, acupuncture and in some cases, surgery. Some medical practitioners have even gone so far as to prescribe placebos for the treatment, which has actually resulted in the lessening or complete elimination of the pain. This may therefore indicate that the condition can be associated with psychological conditions as well as physical.

Chronic Pain
Some individuals with chronic pain can be assisted with the problem by them understanding the root cause of the pain and the relevant steps they can take to reverse what the chronic pain has done. With the advancement of neuroscience, scientists believe that there will be better understanding of the condition and therefore better treatments available in the years to come.
