Tax Deduction for 2019

I was in an accident in 2016 and have had a few surgeries in 2017 & 2018. My doctors suggested low impact therapy to help with core strengthening, my joint pain, & recovery. We had a pool installed in 2019 and was wondering if we could deduct some of the cost? If so, what documents do we need to submit?

 

Please advise! 

Thanks,
