Numbness is also known as paresthesia. It is a sensation of a person’s skin that may be described as pins and needles, tingling, or a limb being “asleep”. Numbness may come and go or be more constant. Constant numbness may be a problem with the function of neurons. This may be due to poor circulation, vitamin deficiency or a metabolic problem such as hypothyroidism or diabetes. Nerves can also become inflamed contributing toward numbness. Neck and spine problems may compress nerves and muscle cramps, bad posture, unsafe lifting practices and physical trauma can all contribute towards potential numbness. Physical therapy can help through a thorough evaluation identifying the problem, trying conservative measures such as education in posture, nutrition, manual techniques to help with spinal alignment and myofascial release, and individualized exercises to increase balance and strength.
