I would speak with an attorney ASAP on the matter.  There is a 3 year statute of limitations on med mal claims but there is a tolling (extension) provision. The consultation should be free.   Here is the law:In Massachusetts, any medical malpractice action for injury or death must be brought within three years after the cause of action accrued, but in no event more than seven years after the alleged act or omission occurred, except in the case of foreign object actions. Mass. Ann. Laws ch. 260, § 4 (Law. Co-op. 1992). A cause of action for medical malpractice accrues when a plaintiff learns, or reasonably should have learned, that he has been harmed as a result of the defendant’s conduct. Teller v. Schepens, 381 Mass. 621, 411 N.E.2d 464 (1980).Good luck.
