3 years post op pain, tingling sensation to my left breast, what could this be?

Your symptoms seem to warrant a follow up visit to your surgeon. He or she can provide better advice after a thorough in person evaluation.

Thanks for your inquiry but without an exam it is is hard to advise. I would say the symptoms you are feeling are not common this far out and it is best to be evaluated by your surgeon, good luck.

It could just be some scarring around your sensory nerves, but I would suggest getting a mammogram and being examined.
