Hello. I Had Colorectal Surgery In March 2016 After A

Hello. I had colorectal surgery in March 2016 after a reoccurring instances with diverticulitis. I have been symptom-free since then but in the last day or two started feeling light pulling in my sternum area. Is this something I should be concerned about ? I'm sure it is non-related just a tad paranoid after really rough health year.
