Reasons You Could Have Numbness or Tingling Sensations in Your Hands

Sometimes, physical structures can directly impinge on nerves. Nerve compression by cysts or tumors can occur when non-cancerous growths, such as ganglion cysts (fluid-filled lumps that often develop near joints or tendons in the hand or wrist), press on nearby nerves. This pressure can interfere with nerve function, leading to numbness, tingling, and potentially also joint pain or restricted movement.
