back pain
"Good at relieving pain for a short duration (4 hours at a time) with few side effects. I found that at 200mg/day my pain was cut in half and I had increased energy and a brighter mood.  I have used this medicine for 4 years now and find that it is very effective for about four months.. and then effectiveness decreases.  At that point, my doctor switches me to a narcotic for three to four weeks and then I can continue with the tramadol over again with a "reset" in the effectiveness factor.  The strongest negative for me is getting off the tramadol... withdrawl effects include major mood swings, insomnia, and dizziness.  But overall, it is quite effective and has very few bad effects for me while taking it."
