Hi and welcome to HCM...
I am really sorry to hear this side effect of yours..
Thank you for posting your query and I'm here to help you out..

I being a surgeon, we encounter so many such cases..
I read your question completely and have understood it well enough..

Tramadol comes under morphine group of drugs and as you have told, definitely all these things are seen...
Remember these following things..

1. All the side effects mentioned with any drug will happen.
But no one can know or predict, what side effects will be seen particularly to a given individual.
And also, the intensity and the frequency..

2. Only after we take a particular drug, one comes to know all these issues..

3. And believe me, these adverse reactions cannot be avoided or reduced.
Yes it can be reduced by taking lesser dose but it's of no use taking a sub standard dose..

4. And coming to your point, you can definitely believe all these side effects listed.

It's just how our body reacts..
Hope I've cleared your doubts, in case you need any further assistance, please let me know.. I'm there for you .
Take care Friend and God bless you..
