Foot Neuropathy Due to Spinal Problems
Nerve pain in the foot normally occurs due to problem in your back rather than in your foot.
When the problem occurs with the function of nerves that regulates the messages from spinal to brain and vice versa. It causes problems in hands and feet. Peripheral neuropathy can develop
- Suddenly: can cause because of a traumatic incident.
- Develop gradually: tends to progress over the period of time and becomes chronic, which results in slow improvement.
If the damage occurs to one nerve it is termed as mononeuropathy and if it damages more than one nerve it is known as polyneuropathy.
The damage caused due to peripheral neuropathy results in
- Weakness: difficulty in moving your leg or lifting up the leg.
- Pain: stabbing, sharp, electric shock which often worsens during night
- Altered sensation: pins, numbness, tingling or hypersensitivity. It makes you feel like you have worn a sock when actually you are barefoot.
- Altered co-ordination and balance
Symptoms affect both feet rather than just affecting one and it progresses gradually.
Causes of nerve pain in foot in case of peripheral neuropathy
- Medical Conditions: Diabetes is the major cause in case of peripheral neuropathy resulting in diabetic nerve foot pain which causes to imbalanced blood sugar levels which disturbs the metabolism of nerves glucose levels. Any diabetic person should take good care of their feet and report their doctor in case they face burning sensation or foot pain.
- Injury: This may come from an incident or repetitive compression.
- Infections: for example shingle, leprosy or Lyme disease.
