Answer 1

the vessels collapse

Answer 2

Pain can be referred from places other than the head. This deals with headaches but the principle works for all kinds of pain.
Muscles get knots called trigger points. These make the muscles tight causing them to press on nerves and other thing.
#1 The first thing is to take a couple swigs of molasses or eat a couple of bananas. They contain magnisium and potassium both of which muscles need.
#2 WATER she should be drinking 1/2 gallon minimum. The head of neurology at UCDavis likens a body running low on water to a car running low on oil (the engine can seize).
Get a good (deep tissue) massage (to loosen the trigger points) on the back, shoulders and neck. Make sure to press up at the base of the skull where it meets the spine.
You rub or lightly scratch everywhere on your head. You will hit spots that are tender these are trigger points. The idea is to rub across them 6-12 times per session up to six times per day until they go away.
For more information on trigger points read The Trigger Point Therapy Workbook by Davies.

Answer 3

You don’t have to get worried about it. It could be because there is not enough blood circulation due to perhaps disuse atrophy or perhaps due to the fact that part of your body was at rest for two or three hours. You can find good home remedies for this. I did find some at http://ailments.in/peripheralneuropathy.html
