Because the peripheral nerves play a role in so many functions in your body, peripheral neuralgia can cause a wide range of problems. You may have numbness, tingling and painful sensations in your extremities. You may have problems with strength and coordination. You may have cramps and spasms in your muscles. You may be sensitive to heat and touch. You may experience problems with your digestive and urinary systems. Your heart rate and blood pressure may be affected. If the autonomic nerves are affected, signs and symptoms might include bowel, bladder and digestive problems, dizziness and lightheadedness.
