A neuroma is commonly known as a pinched nerve. The nerve tissue found between the toes becomes compressed and may create a benign growth. The neuroma may be associated with leg cramps, arch aches, low back pain, and headaches. A neuroma is not limited to between the toes and can occur on different parts of the foot. If neuroma goes untreated, it could lead to long-term damage to the nerve. You may feel a pinching, burning, stinging, or numbness feeling between the toes and even on the ball of the foot. Neuroma makes any physical activity on the feet very difficult.
