Thanks everyone, yes I am very relieved and so grateful for this forum and your support
Ria, glad your lump went away. I have a lump in my leg which appeared in my 20's which apparently is very rare (forget what it is called) and was told it would be a problem for the rest of my life, anyway fast forward a few years and it stopped bothering me. I can walk fine whereas at one point I couldn't. Twinkle is more energetic than ever at the moment (i think he has his seasons mixed up) so it can't be bothering him that much, he has become addicted to his wheel at the moment.
Thanks Coco, I hope my health improves soon too .
