Update. Relative got in but he was laying on bathroom door with his body up against the door so when they pushed to open the door he was blocking it and in pain from having the door pushed on him!
Relative called for an ambulance and they said it’s already in the system. Called the police who said they can’t come and help pick him up.
Called the fire brigade and they were there in seconds and they cut the door in half (mother will not be amused if she finds out! )
They had no restrictions in lifting and helping him up and got him on the sofa and he’s had a drink and a bite to eat.
Fire brigade are absolutely wonderful and I will be sending them a thank you message.
So my dad is now on the sofa but very wobbly. Does not appear to have broken anything but only a medical assessment will decide that for sure.
My cousins husband and my cousin are both with him and waiting for the ambulance as they believe he should be admitted as he is in no state to be on his own as he cannot support his body or walk.
Obviously there is a degree of shock at being on the floor for a long while.
The bathroom is the worse place to fall as everywhere has a smooth surface, walls, floors, bath, sink, toilet etc so it’s hard to grip anything to try and pull yourself up!
He was too shaky to speak on the phone but the huge relief of my cousin and her husband driving there to help is wonderful.
They are older than me but in better health and have said they will have their phone number out on the contact list as the priority number instead of me as they live in the same county as my dad and they will drive over in an emergency. That is fantastic of them.
Funny enough I accidentally put my keys in the boot of my car once whilst out dog walking and my dog promptly sat on the keys and depresses the lock button and effectively locked himself in the car!
I was besides myself and had a panic attack on the phone whilst talking to my car insurers to arrange an emergency call out which I was entitled to. They were bloody useless and were refusing so I hung up. (Got an apology the following day).
A passer by saw me in distress and she promptly called the fire brigade who were there in minutes and they carefully smashes a window and got my keys and reunited me with my dog who had no idea of what had gone on but was delighted to be fussed by the fire brigade!
They are my heroes!
So, thank you ever so much for all your replies, just getting replies is a support and a distraction from panicking so it’s much appreciated.
Essex fire brigade - Thank you!
