@CathrynH .... I hope you are going well in your recovery xx.
Do you have access to a phsyio Exerciser (thru your medical team?) Have you asked them? Everyone heals at a different rate & it is very important not to 'push it'! ;)
How long ago was your surgery? It looks like your previous comments may be in a Private Group?
It is always best to 'make haste slowly' - as any setback from going back too early/too hard may take a lot longer to recover from!
Take care & all the best
