gardenswithchickensinthem I am happy to join your Pity party! But you know you have a serious problem and you can and should take it seriously.
So I managed to do my back in lifting an empty carrier bag while twisting in the doorway of a car (bag was on the car floor)!
I immediately developed a swearing spree and could not move without saying something rude! Luckily, I kind of knew it would not be permanent and within a few days it was better. I used a hot water bottle on my lower back and a heated wheat bag (shaped like along thick sausage) on my neck as I developed a little bit of refereed pain in the neck!
I saw a private physio and it cost under £50 for a first appointment and massage with this machine like a cattle prod. It was very good. It really helped.
I was also given exercises, it is all better now.
IMHO do not do any exercise unless you are told by a professional what to do.
I hope the MRI scan goes well, I mean they find out and sort out the root cause.
Re "Children laugh at my walking (teacher)" can you speak to these children or have your head speak to the class/group? If you had a permanent disability would the children make fun of your walk, would the school turn a blind to children laughing at a teacher?
Re I worry colleagues think I'm putting it on. Please stop worrying that your colleagues think you are putting it on! If they have had serious back pain they should have sympathy and empathy for you; if they have not had serious and almost constant pain, they do not know how lucky they are!
Re People keep asking how did you do it or what have you done and I just don't know! So you can answer honestly, I just don't know how I did it, these things can happen. It is excruciatingly painful." Any attempts by friends or colleagues to dumb down the pain or play down your situation should be met with a simple "I have never encountered pain like this before, I am seeing a doctor/physio/waiting for an MRI and hope that the doctors will be able to sort this out. But in the meantime it is utterly exhausting to be in constant pain."
I am afraid if anyone questioned me more I would need to say "I am afraid I am exhausted I must go and sit down. If you would like to be of help you could get me a cup of tea, please... etc"
Re "Driving is horribly sore and I'm actually scared to cough or sneeze. I never thought the day would come when I was scared to sneeze!"
Can anyone offer you a lift, at least some days?
Coughing and sneezing are things that can cause these injuries, so I think the advice is to not twist while doing it, but please check with doctor the best way to cough or sneeze to avoid further injury.
I don't want to be alarmist but do be careful.

Re " I hate feeding the cats as I have to bend over." put your cats plate on a chair, unless your at is very elderly I am sure they can jump onto a chair.
PLEASE do not let ANYONE make you feel bad for being ill, if there is any suggestion that you are making it worse than it is please just explain very simply, "I am in agony, I am soldiering on with work and finding it almost impossible." or suitable words to that affect. This is what I would do. If you choose to do it, say it in your own words.
Please take your doctors advice about whether you can be being signed off if this is not sorted very soon, it's Easter holidays so I can't imagine the kids are doing that much this week, are they? Mine are breaking up tomorrow. Are you in a union? Check with doc if soldiering on could really be making things worse.
Are you single? Is anyone offering to help you? Anyone asking if they can do anything for you? Friends, family, Facebook friends, colleagues etc etc? *if so, please, please ask for help, making meals, getting shopping in, loading dishwashed etc. Do not struggle on. If anyone offers help you can just ask for a one off 'could you get me XYZ from shops etc?' Then if they ask again to help you can ask them again to do something.
I suggest you make sure you have some cash at home in case you need to pay for shopping or need to get a taxi somewhere.
Good luck. Please do not take any shit from anyone about this, you are ill.
Get well soon.
