As well as physio you could try the local gym (run by the local authority, forget about training for a marathon [!], I believe that there is a scheme/concession for cases referred by their GP). Being a cynic, one could say it is another excuse to save money rather than employing more physiotherapists - BUT, it is physical thearpy in a supportive environment and complements (and even betters) the exercises you are doing. I hope this helps.
Excellent news Mags, OT’s are wonderful. I got a new banister and it’s even better than I thought it would be in helping me up my stairs which curve. I’ve had no falls down them since. It’s fantastic what gadgets they have or can recommend you buy to make life easier. I’m really glad they can help your mobility too, any change for the worse is really distressing. Definitely a good day!!
