From the sounds of it, skin pain, back pain, kidney pain, etc... its all dehydration. If the vomiting and diarrhoea continue for more than 24 hours you should seek medical attention.

During diarrhoea there is an increased loss of water and electrolytes (sodium, chloride, potassium, and bicarbonate) in the liquid stool. Water and electrolytes are also lost through vomit, sweat, urine and breathing. Dehydration occurs when these losses are not replaced adequately and a deficit of water and electrolytes develops.

The volume of fluid lost through the stools in 24 hours can vary from 5 ml/kg (near normal) to 200 ml/kg, or more. The concentrations and amounts of electrolytes lost also vary. The total body sodium deficit in young children with severe dehydration due to diarrhoea is usually about 70110 millimoles per litre of water deficit. Potassium and chloride losses are in a similar range. Deficits of this magnitude can occur with acute diarrhoea of any etiology. The most common causes of dehydration are rotavirus, enterotoxigenic Escherichia coli (ETEC) and, during epidemics, Vibrio cholerae O1 or O139.

Dehydration is the loss of water and salts from the body.

The human body needs water to maintain enough blood and other fluids to function properly. Along with the fluids, the body also needs electrolytes, which are salts normally found in blood, other fluids, and cells.

The body may lose fluids in a variety of ways:

when urinating
when you vomit or have diarrhoea
when sweating
from the lungs during normal breathing.
If the body loses a substantial amount of fluids and salts and they are not quickly replaced; for example: by drinking, the body starts to "dry up" or get dehydrated.

Severe dehydration can cause death.

The usual causes of dehydration are a lot of diarrhoea and vomiting. Dehydration can also occur if you do not eat or drink much during an illness or if you do not drink enough during or after strenuous exercise. Medications that cause fluid loss to control excess body fluid (diuretics) are a common long-term cause.

Although anyone can become dehydrated, those who become dehydrated the most easily are:

babies under 1 year old
the elderly
anyone who has a fever
people in hot climates.
Dehydration caused by diarrhoea is one of the biggest single killers of children in the modern world and diarrhoea itself is one of the major causes of nutritional loss and poor growth.

This year, about 2.2 million children will die of dehydration caused by diarrhoea - 80% of them in the first two years of their life.

What are the symptoms of dehydration?

The degree of dehydration is graded according to signs and symptoms that reflect the amount of fluid lost:

In the early stages of dehydration, there are no signs or symptoms. Early features are difficult to detect but include dryness of mouth and thirst

As dehydration increases, signs and symptoms develop. These include: thirst, restless or irritable behaviour, decreased skin turgor, dry mucous membranes, sunken eyes, sunken fontanelle (in infants), and absence of tears when crying vigorously.

Symptoms of early or mild dehydration include:

flushed face
extreme thirst, more than normal or unable to drink
dry, warm skin
cannot pass urine or reduced amounts, dark, yellow
dizziness made worse when you are standing
weakness
cramping in the arms and legs
crying with few or no tears
sleepy or irritable
unwell
headaches
dry mouth, dry tongue; with thick saliva.
Symptoms of moderate to severe dehydration include:

low blood pressure
fainting
severe muscle contractions in the arms, legs, stomach, and back
convulsions
a bloated stomach
heart failure
sunken fontanelle - soft spot on a infants head
sunken dry eyes, with few or no tears
skin loses its firmness and looks wrinkled
lack of elasticity of the skin (when a bit of skin lifted up stays folded and takes a long time to go back to its normal position)
rapid and deep breathing - faster than normal
fast, weak pulse
In severe dehydration, these effects become more pronounced and the patient may develop evidence of hypovolaemic shock, including: diminished consciousness, lack of urine output, cool moist extremities, a rapid and feeble pulse (the radial pulse may be undetectable), low or undetectable blood pressure, and peripheral cyanosis. Death follows soon if rehydration is not started quickly.

Dehydration
From Wikipedia, the free encyclopedia.

Dehydration is the removal of water (Greek hydros) from an object. There are many methods of dehydration, with the most common being the application of dry heated air. This causes evaporation of the surface water, which is replaced by water internally.
Drying is often used as a method of preserving food and to obtain absolute alcohol.

In humans dehydration can be caused by a wide range of diseases and states that impair water homeostasis in the body.

Examples are :

infectious diseases
yellow fever
cholera
Shigellosis
common gastrointestinal viral and bacterial infections resulting in vomiting and diarrhea, also known as gastroenteritis.
external or stress related causes
Hyperthermia
shock
blood loss or hypotension due to trauma
prolonged physical activity without consuming adequate water, especially in a hot environment
dietary imbalances due to
nausea
restricted salt diets
excessive consumption of alcohol
other causes of obligate water loss or electrolyte abnormalities
severe hyperglycemia in diabetes. Excretion of glucose with urine (glucosuria) is accompanied with water loss. Water is the required solvent.
Symptoms may include headaches similar to what is experienced as a hangover, and lower blood pressure and a dizzy feeling when standing up which is called orthostatic hypotension. Extreme cases of dehydration can result in unconsciousness and death.

Correction of a dehydrated state is performed by rehydration, and the addition of necessary electrolytes.
