Neuropathic pain: When to call

- No bowel movement in 3 days.
 - Blood in the anal area, in your stool, or on the toilet paper.
 - Diarrhea for more than 24 hours.
 
  
 Watch closely for changes in your health, and be sure to contact your doctor if:
  - Your pain is getting worse.
  - You can't sleep because of pain.
  - You are very worried or anxious about your pain.
  - You have trouble taking your pain medicine.
  - You have any concerns about your pain medicine or its side effects.
  - You have vomiting or cramps for more than 2 hours.
