"Waiting time"

Referred to Orthopaedics as urgent for hip ops Feb 2023. Finally had pre op tests 3 weeks ago. Anaesthetist wanted me to have appointments with Prime clinic and an ECHO scan before op takes place. Appointment came for Prime, nothing for ECHO. Hospital rang 5th April to say Prime appointment Tuesday cancelled. Doctor wanted to see results of ECHO scan first. As no sign of ECHO appointment to date, yet another wait. How long this time.The physical and mental strain of waiting 15 months so far, is worrying.Struggling up and down stairs to use the bathroom is a nightmare.Yesterday I had to make 3 attempts to climb a step to get into my bedroom.How long before I can't do it? Hospital seems to think adding another 3 months on your waiting time is ok. It is not, particularly when you live alone, and pain and severely diminished mobility is involved.
