Swelling in feet ok in the morning? i find after sitting for a while that both my feet swell. in the morning they are back to normal. could this be an ab fib issue or just a vein issue? thanks?

Medical evaluation : Swelling of the feet can be caused for a number of reasons.However given the fact that you have a history of a fib that would be a likely place to start. Whatever you decide do not allow this to continue without seeing medical assistance. This is a warning sign of something else happening in your body. Other organs in your body can be involved so therefore please do not hesitate to seek follow up
