I was just saying what it says in the medical info released with tramadol.
'
Tell your doctor if you notice any of the following side effects or notice any other effects not listed:
...Extreme sense of wellbeing (euphoria), false sense of uneasiness (dysphoria), confusion, hallucinations (sensing things that are not real), altered mental state (delirium), changes in ability to think or sense clearly, sleeping problems (including nightmares),
fits, blurred vision, slowed heart beat, high blood pressure, changes in appetite, muscle weakness, difficulty urinating...'

This is among the rarer side effects but note some of the others in the same bracket. It's reasonable to assume that recreational doses up the risk of these effects as on rec doses I've had all of the 'very common' side effects, six out of ten of the 'common' side effects, three out of ten of the 'uncommon' side effects and from the 'rare' I've got what I was aiming for, namely the euphoria, the changes in ability to think clearly, sleeping problems, blurred vision, changes in appetite and difficulty urinating. Ok I wasn't aiming for the last one.
I really don't think it's safe to propagate the claim that tramadol does not increase the risk of seizures.
