Tramadol Hydrochloride and back pain

I seem to be lucky, due to back accident17 years ago I have suffered with aching back at night,(I had knee ligament operated on last year and that pain is how I describe my back pain)(before op),I`ve tried co-codamols and anti-imflams to help back pain,didn`t work,physio,didn`t work but with Tramadol it eased it straight away,I do occasionally get itchy skin with it but then I always have suffered sensitive itchy skin,so I can deal with that,I also find this as a bit of a miracle drug,since suffering a virus over eleven years ago I`ve since suffered with feeling tired all the time and with no energy but again since taking ?Tramadol for my back its brought me up to a better level, It doesn't make me feel drowsy,maybe after reading other peoples experiences with Tramadol it looks like it works for some and not for others,just like all medication.
For me its a blessing.

headaches left side,increased need to urinate, itchy skin, feeling nauseous I have only been taking this drug for 2 days for back pain, but already I feel dreadful, although the backpain is a bit better.
