6. You May Have an Infection
Tingling sensations could be symptoms of infections; in particular that of shingles, herpes or HIV. Even after shingles or herpes outbreaks subside, symptoms of paresthesia may continue for the short or long term. In most cases of these infections, tingling sensations come and go.
5. You May Have an Injury
Were you recently injured? Nerve compression or damage caused by an injury could cause tingling hands and feet. Two injuries commonly resulting in paresthesia could include a herniated disc and sciatica. These two conditions are related to radiculopathy.
Radiculopathy, as explained by Johns Hopkins Medical, is the collection of symptoms related to pinched nerves in the spinal column. These pinched nerves can result from injury and cause symptoms of tingling or prickly sensations.
4. You May Have Symptoms of Systemic Disease
A systemic disease is one that affects the whole body. Tingling of hands and feet could be symptoms of systemic diseases like diabetes and leukemia.
However, it’s important to note a distinction between compressed nerves of paresthesia and the nerve pain from nerve damage called peripheral neuropathy.
The constant battle of glucose regulation of diabetes can damage blood vessels and nerves, which can cause tingling or prickly sensations from peripheral neuropathy.
