Seeing your GP for a firm diagnosis is the correct course of action - hope that it goes well.
Yes, I have an appointment next week. You do get treatment with the NHS, albeit slowly. The thing is to get it started and then chug through the system, but as I have suffered from depression in the past I'll lay that on a bit to see if I can speed up the process
Interestingly I have been on two day walks recently, around the Pendle district of East Lancashire
The first was with a walking group, and my legs ached quite a bit for a few days afterwards. But that included some uphill, and I was keeping up with the others, even though it was not a particularly fast pace. It's the sort of thing that I would never have bothered me, but obviously in my present state I found it harder
Yesterday I went on a walk on my own; along the canal, across fields, and at my own pace. I managed that quite happily, so there's hope yet
I've been Searching t'Net & YT, the recommendation is that more walking & exercise will improve things; let's see what the doc has to say
We all know that there's going to come a day when we can't do what we did when we were 20, but keep hoping 'not yet.....not yet....'.
