Nerve Compression: When pressure is placed on nerves in any part of the body, severe pain and tingling can occur. For example, Carpal Tunnel Syndrome, which compresses the nerves in the wrist, causes tingling and pain in the hands.
Herniated Disc: When the discs in the spine slip and press on the nerves, severe pain and tingling can spread from the back or neck to the arms and legs (e.g. sciatica).
Diabetic Neuropathy: In people whose diabetes is not controlled for a long time, nerves become damaged, causing chronic pain, numbness, and tingling in the feet and hands.
Vitamin Deficiency: A decrease in vitamin B12, which is necessary for the proper functioning of the nerves, is a major cause of such difficulties.
Circulatory disorders: When blood flow to the limbs is reduced or blocked, oxygen is deprived, which can lead to pain and numbness.
Excessive stress/posture: Sitting or lying in the same position for long periods of time can temporarily restrict blood flow to the nerves, causing numbness.
