I am in the UK and will be flying to o hare and transiting 11 hours later to Miami. I am 78 years of age and suffer from arthritis. What facilities are available. Example lounges and transport. Thank you Michael

Contact your airline for wheel chair services. There are airline lounges available that you can buy a pass for the day. There are many sit down restaurants, but most close for the evening.
