Health concerns For Olivia Newton-John

Olivia Newton-John has been forced to postpone her upcoming concerts due to health woes.

The legendary actress, 68, made an official announcement via Facebook on Wednesday, a day before she was scheduled to perform in Battle Creek, Michigan.

The post confirmed that her An Evening with Olivia Newton-John tour dates for May would be rescheduled due to ongoing struggles with sciatica.

'We are so sorry to announce that the Olivia concerts scheduled for May will be postponed due to a bad issue with Olivia's sciatica,' a statement read.'Once the dates are rescheduled we will post the new dates ASAP. Apologies for any inconvenience.'

'Once the dates are rescheduled we will post the new dates ASAP. Apologies for any inconvenience.'

The Grease star was set to perform in the US and Canada this month, however she will instead undergo treatment for ongoing pain along her sciatic nerve.

Sciatica affects the lower body, with pain typically running down the lower back and legs. 

While in some cases surgery is required as part of the treatment process, it is unclear whether Olivia will undergo any surgery.

Earlier this year, the star reflected on being diagnosed with breast cancer two decades ago and getting a mastectomy saying it 'taught her compassion.'

'I am grateful for the experience because without it I would not have done many of the things I have done in my life,' she told Radio Times.

'It's taught me compassion for those going through difficult times.' 

She added: 'Having cancer forced me to think deeply about myself for the first time, so it was a positive experience in that respect. I learned not to feel guilty about my successful music career.' 

Olivia has since been an activist in the fight for a cure and in 2008, she opened the Olivia Newton-John Cancer and Wellness Centre (ONJCWC) in her hometown of Melbourne, Australia.
