Pain Flashcards
What is nerve pain?
Sharp Lancinating Bright Burning Shooting Pins and Needles Often following pathway of nerve
Ie: nerve root impingement, traction injury, carpal tunnel, sciatica
What is Bone Pain?
Acute Sharp Severe Intolerable Ie: Fracture
Other:
Deep
Boring
Very localized
Ie: bone bruise, metastatic bone cancer
What is Joint Pain?
Acute:
Sharp
Localized
Ie: Grade 2 ACL tear/sprain, labral tear, meniscal tear
Subacute/Chronic:
Dull
Achy
Can be localized or not
Ie: Chronic Ligament tears
What is Muscular Pain?
Dull
Achy
Cramping
Often not localized
What is Vascular Pain?
Diffuse
Achy
Throbbing
Ie: coronary artery disease, vasculitis
What is Visceral Pain?
Diffuse
Achy
Poorly localized
Ie: appendicitis, IBS, food allergies
4 Types of Behaviour of Pain
- Constant
- Mechanical
- Episodic
- Irritability
What’s Constant Pain?
Unrelenting pain, even at night
Pain may fluctuate in severity but is always present
Typically chemical in nature, inflammation activates local nociceptors
RED FLAG FOR TUMOURS, VISCERAL LESIONS, CHEMICAL IRRITATION
What is Mechanical Pain?
Brought on by certain movements
Related to stress on a specific anatomical structure
MCL sprain, meniscal tear
What is Episodic Pain?
Related to specific activities, postures
Tends to come and go
Increasing frequency as time progresses
Often related to an ongoing disease process
Ie: DDD, facet joint syndrome, IBS
What is Irritability Pain?
Refers to the ease with which symptoms can be exacerbated
Indicator of stage of healing
Peripheralization vs. Centralization
P: Vs. C:
Pain travels further from source. Pain travels closer to source
Pain decreases in intensity. Pain increases with intensity
Occasionally pain will disappear at the source of irritation
When does Chronic Inflammation pain occur?
Typically presents as morning stiffness and pain with improves with activity
When does Joint or Soft Tissue Inflammation pain occur?
Typically presents later in the day as the patient as placed more stress on the tissues
When does Tumour pain occur?
Night pain, constant pain, often accompanied by fatigue and weight lose in later stages
Acute Stage
Inflammatory Stage
4-10 days (1-4 days)
Goal: Restore tissue homeostasis
Process:
1. Clotting ~ increased local blood vessel permeability causes a leakage of plasma proteins and the formation of an extravascular clot
- Chemical Mediators:
Bradykinins - attracts neutrophils and macrophages
Neutrophils - help clear bacterial and fungal pathogens
Early inflammation stage
Macrophages - same as neutrophils but also clear out dead cell
Cells and debris, releases platelet growth factors
To lay doesn’t foundation for the proliferation phase
Later Inflammatory Stage
Function of a clot?
- To hold would edges together
- To create a mechanical barrier to foreign material entering the wound
- To help prevent spread of infection
What other structures also release Platelet Derived Growth Factors (PDGF)?
Platelets
Smooth muscle cells
Endothelial Cells
Signs of Inflammation
- Heat/Redness
- Pain
- Swelling
What is Inflammatory Exudate?
A fluid rich in protein and cellular elements that oozes out of blood vessels due to inflammation and is deposited in nearby tissues
Includes: Gamma Globulins
Leukocytes: Neutrophils, Macrophages, Lymphocytes,
Basophils
Treatment goals for Acute Inflammatory Stage
- Decrease Bleeding: RICE for first 24/48 hours, NSAIDS
- Decrease pain: RICE first 24/48 hours
- Help remove excess inflammatory exudate a: METH
- Promote good scar tissue adhesion: gentle ROM within pain
Tolerance, gently massage, pulsed ultrasound
M.E.T.H meaning
Movement
Elevation
Traction
Heat
Subacute Phase
Proliferation Phase
10 days - 7 weeks (4-6 days to 15 days)
Goal: Granulation and Scar Tissue Formation
Process:
1. Granulation tissue is new connective tissue with capillaries that form on the surfaces of a wound during the healing process.
- As each new capillary loop brings nutrients and oxygen to cells, fibroblasts are able to build more matrix and allows more macrophages and cells to migrate. Fibroblasts develop into myofibroblasts (wound contraction)
- Collagen Fibers (Formed by fibroblast) are formed and if left on their own form bundles that are not oriented in any particular direction. Coleen at this stage is weak and vulnerable to tearing
What does Granulation Tissue consist of?
Macrophages
Fibroblasts
Endothelial Cells
