Hypoglycemia Unawareness. Normally, symptoms such as shakiness, sweating, and palpitations occur when blood glucose levels drop below 70 mg/dL. In people with autonomic neuropathy, symptoms may not occur, making hypoglycemia difficult to recognize.
Proximal neuropathy.Proximal neuropathy, sometimes called lumbosacral plexus neuropathy, femoral neuropathy, diabetic amyotrophy, or radiculoplexus neuropathy starts with pain in the thighs, hips, buttocks, or legs, usually on one side of the body.
This condition is often marked by:
- Sudden, severe pain in your hip and thigh or buttock
- Eventual weak and atrophied thigh muscles
- Difficulty rising from a sitting position
- Abdominal swelling, if the abdomen is affected
- Weight loss
This type of neuropathy is most common among those with type 2 diabetes and in older adults with diabetes. Proximal neuropathy causes weakness in the legs and the inability to go from a sitting to a standing position without help. Treatment for weakness or pain is usually needed. The length of the recovery period varies, depending on the type of nerve damage.
Mono-neuropathy or Focal neuropathy. Mono-neuropathy, which may also be called focal neuropathy, often comes on suddenly. Mono-neuropathy involves damage to a specific nerve. The nerve may be in the face, torso or leg. It’s most common in older adults. Although mono-neuropathy can cause severe pain, it usually doesn’t cause any long-term problems. Symptoms usually diminish and disappear on their own over a few weeks or months. Signs and symptoms depend on which nerve is involved and may include:
Inability to focus the eye, double vision, aching behind one eye
- Paralysis on one side of the face, called Bell’s palsy
- Severe pain in the lower back or pelvis
- Pain in the front of the thigh
- Pain in the chest, stomach, or side
- Pain on the outside of the shin or inside of the foot
- Chest or abdominal pain that is sometimes mistaken for heart disease, a heart attack, or appendicitis
People with diabetes also tend to develop a condition where the nerves compress called entrapment syndromes. One of the most common is carpal tunnel syndrome, which causes numbness and tingling of the hand and sometimes muscle weakness or pain.
