As I Lay Dying singer Tim Lambesis is filing a $35 million lawsuit after he was allegedly denied medication that he was taking before his imprisonment.

A court document, which was reported by Loudwire, reads: “A nurse, doctor, and psychiatrist at the San Diego County Sheriff Department’s Vista Detention Facility and George F. Bailey Detention Facility acted with deliberate indifference to his serious medical needs in May and June 2014 by denying him medication which had been prescribed for him prior to his incarceration.”

A separate court document, which is available through CaseText, names the medication as anastrozole; “a medication prescribed to combat the side effects of withdrawal from anabolic steroids.” The filing also says his nurse, Mary Abiaro, “failed to log his anastrozole prescription into his medical record,” which resulted in a delay in receiving his medication.

Lambesis attests that he underwent ‘exponential terror’  as a result of the 10-day period without his prescription, and now “suffers from gynecomastia due to the hormonal imbalance caused by the failure to receive his prescribed medication.” Gynecomastia is the enlargement of male breast tissue.

Loudwire also reported that while California District Court Judge Michael Anello granted Abiaro partial dismissal of the lawsuit, the medical negligence claim will proceed at an unannounced date.

Lambesis is currently serving a six-year prison sentence after he was incarcerated in May 2014 for attempting to hire a hitman to kill his estranged wife.
