Injured ankle

I'm still waiting to see if they will do surgery on my ankle. Work have sent a letter stating that they would move my workstation downstairs so I can go back. I'm not sure I want to do that, I can still get a sicknote. I have a few issues with the way I've been treated at work throughout this situation. Can I refuse there offer and get another sicknote. 

I went to physio yesterday and he made me an appointment for me to see the surgeon in 2 weeks, he says there's not any point in waiting as it's not getting better. He thinks the surgeon will suggest an MRI. Because of this I've decided to not go back to work until I know what's wrong with my ankle and what can be done. We know I have a complete rupture of 1 ligament but the damage that was seen on the ultrasound to do with the deltoid ligament on the inside is not fully known, plus, he thinks I have nerve damage because I can't flex my foot or turn it inwards and my toes are numb. 

Now I have a huge problem. Went to see the surgeon yesterday (not the one I was supposed to see) he asked me what I had done, I told him. He then said oh these xrays and scans are old but you have ruptured a ligament with an avulsion fracture. He then pressed in 2 spots on my ankle and said can you stand on your tiptoes. He then asked if I had any other health problems I said fibro, schizoaffective and malignant hyperthermia. I asked him if he knew what that was he said something to do with anaesthetic and that's when the problems began. He then went on to ask me how many times has it happened and does it happen every time you have an anaesthetic, stupid thing to say it only happened once, nearly killed me and won't happen again cus I can't be put to sleep. He then said well this is the problem I can fix your ankle but if you have a spinal block it can stop working halfway through the surgery and then we will have to put you to sleep and you won't want that will you. I have had 3 knee surgeries under spinal and no one has ever mentioned this to me. He then said your ankle is called a sprain, a full ankle sprain we should go down the none surgery route and you should where your boot, take painkillers and use your crutches, I said how much longer do I give it before something needs doing he said a year. A bloody year what is going on. My ultrasound was done in August the technician said he couldn't see properly it was too swollen and I would need and MRI, the physio has said the same and the surgeon just wanted me out the room. Come back if no better in a year, what if I worked on a building site, I can't work for a year. He never asked my job by the way. I can't drive, so I can't take the kids to school for a year, I don't have kids but again he never asked. The more I think about it the more stupid this sounds. Then to finish the meeting yesterday he said I can fix it though we will just have to talk again about the anaesthetic. What is going on here. What do I do now

Part of me wants that too so I know it will be better but part of me doesn't because I don't like having surgery and the pain that comes with it. If they find nothing other than the ruptured ligament and avulsion fracture then it's going to be a very long revovery

My ankle is getting worse everyday, walking on it for even a short time is really causing me terrible pain. I really hope this can be sorted because I don't know how I can live like this. Most of my day is spent sat down I only go out for about 2 hours a week. I'm really starting to worry what if they can't do anything about it, the physio I'm having is useless. I've still not had the MRI yet, but I'm getting really worried now 

No, he said 2 to 3 weeks that was a week and a half ago 

Yes it really does help using the crutches and wearing the boot, although I can't walk for as  long as I could a month ago, it's definitely got worse this last month. I don't use them around the house, I have to be really slow and careful. It seems to be that weight bearing is the problem and any uneven ground
