I had a breast reduction on 6/11/15 and been out of work on Short term. I just noticed that a needle may have been left inside
Your best bet would be to return to the surgeon who performed the reduction surgery and discuss your concerns with him or her. Until you know for sure whether the poking is from a foreign object (i.e. needle, surgical tool, etc), there is no way to know whether medical malpractice has occurred. Once you find out the cause of the discomfort/poking, if you wish to discuss a malpractice claim, please feel free to contact me and I would be happy to discuss with you.
Best of luck.
