What are the withdrawal symptoms of tramadol?

Personally I did not have any withdrawal problems. May not have taken Tramadol long enough to cause any symptoms.

Early in the process, the individual is likely to experience:

Anxiety.
Agitation.
Muscle aches and pain.
Fever.
Poor sleep.
Runny nose.
Watery eyes.
Increased sweating.
Frequent yawning.

After some time, these effects will give way to later symptoms of tramadol withdrawal like:

Cramping in the abdomen.
Dilated pupils.
Diarrhea.
Goose bumps.
Nausea and vomiting.
Muscle spasms.
