It is important to remember that MS is only one part of a person and not the person.
MS does not represent them, it is not their identity, they are as normal as the next
person.

MS Hug - Girdle Band Sensation
Caused by a lesion on the spinal cord and is classified as a neuropathic pain (paresthesia)
which refers to any abnormal sensation. The sensation itself is the result of the
intercostal muscles going into spasm. MS hug symptoms vary from person to person
and they may also vary in the same person at different times during the day or days.
The intercostal muscles stretch from the back of the chest area around to the front
encircling the rib cage, when the control signals to and from the intercostal muscle
system are disrupted they may contract when they should be relaxing or relaxing when
they should be contracting (don’t forget muscles do not push they only pull).
There is no set pattern, it is the ensuing signalling chaos created by spinal lesions
which causes MS hug symptoms.
MS Hug symptoms may occur
At waist level or chest level, it is unusual to experience MS hug - girdle band sensation
as high as the shoulders or neck.
It may focus in one small area or go all the way around the body.
Symptoms presents itself as waves lasting seconds, minutes, hours or may even persist
for longer periods of time.
MS Hug symptoms vary from person to person and are often described as
Burning pain.
Constricting sensation.
Dull pain.
Intense pressure.
Sharp pain.
Tickling.
Tingling
Difficulty breathing can be so severe that it is often perceived as a heart attack
or panic attack.
Tests may be done to discount other causes such as
Gallbladder problems.
Gastrointestinal disorders.
Heart problems.
Inflammation of the cartilage between the ribs.
Lung disease.
While MS hug can be a sign of an exacerbation, it can also be a sign of a pseudoexacerbation,
a temporary worsening of symptoms caused by an external factor, such as:
Auto-suggestion - Close your eyes and picture different images that represent the
sensation, then visualize doing something to get relief.
Increase Fluid Intake - Try lukewarm herbal tea for relaxation and plenty of water,
trapped wind will cause discomfort and pain and may be mistaken for MS hug.
Massage - Manual lymph drainage massage can be helpful, however be sure to learn
the correct method. Massage is not always appropriate and can be harmful if applied
when suffering certain diseases. (Always consult your clinician).
Pressure - Place the flat of the hand where possible onto the area and press fairly
hard.
Always wear Loose Clothing - Tight fitting garments prevent the body from breathing
or losing heat.
For some heat helps, for others it makes the problem worse (Uthoffs Phenomenon).
Try a warm bath, warm / hot shower or heating pad to see if this provides some relief.
If you feel an MS hug beginning and heat exacerbates the situation, try cooling off
and resting. (lying flat may be better than sitting when resting).
Many of the medications used to treat “MS hug” are very addictive, use only with
caution and careful monitoring by your clinician.
Intercostal Muscles
There are tiny muscles between each rib, called intercostal muscles which basically
hold the ribs together, giving the ribcage some flexibility while assisting in movements,
such as forced expiration. The intercostal muscles fill up the spaces between the
adjacent ribs. They are arranged in three sets, external, internal and innermost
internal, eleven pairs of each.
Breathing
Inhale - the intercostal muscles contract which raises the rib cage up and outward,
and the diaphragm moves down, making the chest expand. Air is sucked into the lungs,
because the pressure in the airways is less than it is outside.
Exhale - the intercostal muscles and diaphragm relax the ribs fall downward and inward,
and the diaphragm springs back into a dome shape, gently squeezing the lungs and
pushing air out.
Intercostal muscles
Layers of muscles between each pair of ribs linking them together.
There are three principal layers;
External intercostal muscles, which aid in quiet and forced inhalation. They originate
on ribs 1-11 and have their insertion on ribs 2-12. The external intercostals are
responsible for the elevation of the ribs, and expanding the transverse dimensions
of the thoracic cavity.
Internal intercostal muscles, which aid in forced expiration (quiet expiration is
a passive process). They originate on ribs 2-12 and have their insertions on ribs
1-11. The internal intercostals are responsible for the depression of the ribs decreasing
the transverse dimensions of the thoracic cavity.
Innermost intercostal muscle, the deep layers of the internal intercostal muscles
which are separated from them by the neurovascular bundle.
Both the external and internal muscles are innervated by the intercostal nerves and
are provided by the intercostal arteries and intercostal veins.
Their fibres run in opposite directions
Diaphragm
Dome shaped muscle dividing the chest and abdomen areas. In conjunction with the
intercostal muscles they form the body’s main breathing muscle system.
Muscles are in a constant state of readiness (tonus). Although muscles work in pairs
and groups to create movement a muscle can only contract (pull) while the opposing
muscle relaxes and vis a versa, however tension is always maintained in both muscle
pairs (tonus) otherwise instability will occur.
Tension maintained in the relaxing muscle prevents the contracting muscle from overreacting.
Now imagine that the nerve signalling to the muscles are intermittent and the relaxing
muscle or muscles receiving message to maintain its opposing tension its disrupted
it will no longer work to maintain the equalising balance and its opposite partner
will then over react leading to the symptoms of MS Hug.
