What Causes Tingling and Numbness in the Hands?

7. Lyme Disease

A common tick-borne illness, Lyme disease can cause strange sensations in the fingers and hands. Individuals who live in grassy or heavily-wooded areas are more likely to contract Lyme disease because that's where disease-carrying ticks thrive. A small, red bump that expands to become a large circle is usually the first sign, and it can take weeks to months before neurological issues begin to occur. Even when an infected tick bites a person, it's unlikely they will get the disease unless the tick remains attached for over 36 hours.
