Help with exercise suggestions, please?

Does your GP have a physio attached? If so, you might be able to get a telephone appointment.

Thanks, growstuff, that's helpful, I'll see if there is one I can contact.

If there are any ideas for 'self starter' exercises from anyone who might have been in a similar situation (apart from lockdown of course) I'd be very interested to to hear about them. Thanks.

Google Michelle Kenway.
She’s an Australian physio who has a variety of suitable exercises on her website and YouTube. I found them very helpful whilst waiting for my op.

Have a look at stressnomore.com lots of useful gadgets and information here including dvds and books by the aforementioned Michelle Kenway. I didn't know she has a website and exercises on YouTube, thanks thisisnotme.

You can do upper body exercises with tins if you don't have proper weights. If you can get hold of elastic bands (exercising sort) there's also a variety of exercises you can do which don't put too much stress on the core. Avoid legs, bums and tums exercises like the plague. If it's not uncomfortable, you can even do "step" exercises on your stairs.

I do online yoga. I used to go to classes and the teacher has set up sessions on Zoom. I like them because I'm with familiar faces. There are loads of yoga and pilates exercises online. Be selective about the ones which feel comfortable.

I'm a bit reluctant to advise anything because I'm not qualified and I don't know anything about your medical history. That's why I suggested professional advice.

Thank you everyone. No luck with a physio appointment but I have had a quick look at the Michelle Kenway site and it looks very relevant to my situation. The replies she gives in the comments sections are also extremely detailed and useful. I think I should be able to find something helpful there which is comfortable and doesnt make things worse. Thanks for your suggestions, growstuff, yes, I've got lots of tins, so will look for some gentle upper body exercises with "weights". It's very nice to get these positive suggestions. Thanks to everyone who has taken the time to reply to my post.
