Thanks for the details, I have downloaded it to my Kindle this morning, there were quite a few different ones, so the authors helped.
Talking, make sure you are taking your Solpadine AND Ibrufen, you can alternate every two hours one, then two hours another, so you are taking them every four hours or so each. It is really important to do this, as you may think they are making little difference but the accumulative affect will bring relief, don't miss them, even if you feel better, don't dismiss them either.
There are still lots of other drugs you can go for too if it continues, so you really are on the basics at the moment, do don't panic. I think you are doing brilliantly if you got up again - DON'T do the stairs, it is so tempting to be a hero, but don't!!!!!
You do need to tell your OH that the next 48 hours are critical, do the right stuff now and you can save a week. It's the Tamadol that is making you sleepy, so get on top of the pain too, then the Tramadol will be incidental.
Mellifera is right, each time you push it, the spasms continue to protect your discs, allow them to heal, the Ibrufen will help with the inflammation, even though you may not be aware of it.
It seems like a battle, it isn't, you don't need to battle your body, listen to it, if it says no, it means no! The time will come when you can push it a little.
It's heartbreaking not being able to do stuff, especially with your little one, but it won't be for long. My daughter is 11 and it is hard to explain I can't bend down and cuddle or lie on the bed with her as she drifts off to sleep, but this too will pass and like you, I will get back to normal.
Be kind to yourself, explain the process to OH and let your Mum have her grandchild for a night - if anything like my Mum, she will love being needed and helpful - look at it as a service to her!!!!
