I've had my pre assessment today & couldn't believe all I was told. I will have to Inject myself for two weeks before & after & wear surgical stockings for 4 weeks. I'm 68 & just feel it's too much for me. I definitely do not want to inject myself twice a day. Once my knee is better I will start to gently excerise & improve my diet & help myself that way. I've never heard of anyone having to inject themselves, my neice never had too. Its all too much. Sorry.
