It would seem you have a bad reaction to Tramadol, see whether your physician with prescribe an alternative.
It sounds as if you may be allergic to it. I would not take any further tramadol as allergic reactions tend to receive more severe with each exposure to the allergen.
I was recently subscribed tramadol and suffered the same with extreme itching and feeling very drowsy. I returned to my doc and he changed them to dihydrocodeine and these have given no side effects what so ever, much better )
This is one of the expected side effects when taking Tramadol Hydrochloride. Let your pharmacist know about this..
