Hi There
My best wishes to you.
My ds (4 yo) all of a sudden found that he couldn't walk. Before his afternoon nap, all ok, after nap, couldn't walk.
We took him to a and e and they immediately admitted him to hospital. Within a few days, they diagnosed a bone infection (osteomylitis). He stayed in hospital for 4 weeks on an antibiotic drip. The good news is that he's walking again and so far, no reinfection. The bad news is that it's tough emotionally and physically on the parents and the child. Trying to sleep in an NHS hospital children's ward is like trying to sleep in a supermarket - the noise just doesn't stop. Holding a child down for blood tests and canulas is emotionally waring too after a while.
If it is a bone infection, don't worry as your child should make a full recovery. I felt so awful about feeling sad about my child when the child in the next ward was receiving chemo and wasn't responding well and he was unlikely to leave the hospital again.
I do wish you all the best.
