Vicious circle this. I have no energy to work out due to medication. That then keeps me technically obese. The only ever issue I had when I was 7/8 stone was shin splints which went away with persistence on the treadmill but that was when I was full of energy. Now at 14 stone, 165cm height it's impossible.
My doctor followed up and has confirmed sciatica, lower disc relapse. I had a MRI scan some time ago, results were no issues detected. Bloody shooting pains up my body that conveniently occur at bed time are ace

I didn't even know what sciatica is, still don't to be honest

just keeping calm and carrying on...
