I am not sure which procedure you had but if it was the standard Ivor Lewis then the Thoracotomy is most likely responsible for the altered sensation in your right arm/hand.
Also If during the op your right arm was strapped up (to improve access to the chest cavity) then impaired blood circulation can cause neuropathy -- think cramp/pins and needles times ten.
This happened to me and for the past 24 years the fourth and fifth fingers on my right hand have been numb and 'fizzy' !
I will post a pic diagram which will help to explain this possibility.

From which it is reasonable to suppose that during an IL operation there can be collateral
damage resulting in temporary or permanent impairment of function.
*For the record this is not an artist's representation; it is an absolutely anatomically correct digital rendering.
