Thanks for the replies and I am aware of the CAA advice.
I am flying and have been since six weeks after the operation in March,now am flying on an NPPL.
I wanted to know if there would be any adverse effects from aeros,and I will be flying with an instructor.
I spoke to CAA and NPPL medics yesterday and they thought I would be OK flying aeros,just to take it easy to start with and stop if not feeling well.
