πDistribution of cervical nerve roots (C4 - C8)
βοΈ Cervical Nerve Root Distributions
βοΈPlaces where pain goes
βοΈThe affected muscles
βοΈThe kinetic functions of each nerve root outside of the neck vertebrae.
π³This information is used to identify any compressed nerve when there is pain, tendency, or weakness.
βββββ
πΉ C4
π»The Pain :
γ Top of the shoulder
γ The neck
The muscles :
γ Semi-permanent ( Trapezius )
γ Rhomboids ( Rhomboids )
Function :
γ Shoulder Elevation
π Note:
C4 pain is usually positioned in the neck and shoulder without going down to the hand.
ββββββ
πΉ C5
π»The Pain:
γ Outer side of the shoulder
γ The upper arm
The muscles:
γ Deltoid (Deltoid )
γ Biceps ( Biceps )
The job:
γ Sn**ch the shoulder
γ Bend the elbows
π If C5 is affected:
It's hard to lift arm sideways or carry light objects.
βββββ
πΉ C6
π»The Pain:
Outer arm
Thumbs up π
The muscles:
γ The biceps
γ Wrist basins
The job:
γ Bend the elbows
γ Stretch the wrist
πVery popular with cervical disc
Pain + tilt in thumb and weakness in the grip.
ββ
πΉ C7
π»The Pain:
γ Behind the arm
γ Middle finger β
The muscles:
γ Triceps (Triceps )
The job:
γ Elbow individual
γ Bend the elbow
π The most nerve stem affected by the disc
Weakness to push or push ups.
βββββ
πΉ C8
π»The Pain:
γ The inner thigh
γ Pinky and pinky π€
The muscles:
γ Finger twists
The job:
γ Bend the fingers
γ The power of the grip
π If C8 is affected:
Weakness of grip + difficulty of holding small things.
βββββ
π This plan helps doctors and therapists to:
Determining the nerve pressure level
Diagnosis of cervical disc or herniated slip
Attaching the pain spot to the injured paragraph

First off: How to differentiate nerve pain and muscle pain? π§ πͺ
π΄ Nerve pain
γ Extends from neck to arm or fingers
γ The sensation of loading / electric / burning
Yazid with:
Shake That Neck
Bend over or roll over
Clear weakness in a certain movement.
π΅ Muscle pain
γ My situation in one place
γ A feeling of pull or heaviness
γ Getting better with a massage or a warm up
γ No taping or shivering
π A golden rule:
> any hand pain + tendon = often a nerve not a muscle
ββββββ
Secondly: simple tests to find out which nerve is affected π
β οΈTest without violence or extreme pain
ββββββ
π΅ Test C5
Raise your arm sideways (like side flap exercise)
β pain or weakness = possibility of C5 affect
βββββ
π΅ Test C6
γ Both elbows ( biceps )
γ Extend the elbow back β
β Weakness or pain with thumb tilt = C6
βββββ
π Testing C7
γ Push your arm forward or down (like push ups)
β Weakness or pain behind the arm = C7
βββββ
π΅ C8 Test
γ Hold your fist tight
Try to catch a small thing
β Weakness + inclination in the pancreas and pancreas = C8
βββββ
3: What do you do at the gym if you have nerve compression? ποΈ
β Exercises increase the problem
High Bar Squats
Back shoulder press
Deadlift without a neck fixing
ββββ
β
Safe and beneficial exercises
γ Hardware workout instead of bars
γ Slightly inclined chest press
γ Front pull with a neutral grip
π³Shoulder plank strengthening exercises
Fourth: Neurodivergent exercises (safe)
πΉ Chin Tuck (Chin Pull)
γ Pull your chin back
10 seconds x 5 times
βββββ
πΉ Side neck extension
γ Slowly head tilted
20 seconds each way
βββββ
πΉNeural Glide
γ Open the arm
γ Stretch out the wrists and fingers
