Paresthesia is a feeling of tingling, numbness, or “pins and needles.” Everyone experiences this feeling at some point in their lives. In most cases, it's a harmless sign that a limb is “asleep” and that you need to change position or move. But when it doesn't go away or happens often, it can be a major symptom of a medical condition. Dysesthesia is a group of symptoms that revolve around unusual sensations based on touch. It can refer to unexpected or unpleasant, painful, or simply strange sensations.
You may feel these feelings for an obvious reason or you may find it difficult to pinpoint a specific cause. Neuropathy and fibromyalgia, although both involve chronic pain, have unique characteristics that make their correct identification crucial for adequate treatment. Neuropathy is characterized by localized pain due to nerve damage, while fibromyalgia presents generalized pain along with fatigue and cognitive disorders. Peripheral neuropathies present as pain, numbness, tingling, and sometimes weakness.
Initial symptoms generally depend on the nature of the underlying nerve damage. If you constantly feel feelings such as numbness, tingling, or weakness in your extremities, these could be signs of peripheral neuropathy. Paresthesia is the name given to the tingling and tingling sensation felt when sitting incorrectly or sleeping on a limb and then moving. Paresthesia is the tingling sensation that occurs when you change position and release pressure on the nerve or blood vessels in that part of the body.
