What led you to have L4, L5, S1 fusion? Did it happen in one go?

I have a very high pain / uncomfy threshold from ultra running so I don’t know what’s for me and willl cause future damage.

At the moment, my calf and hamstrings get really tight - feels like the next day after running 50 miles. The issue is triggers when I am just sitting down, standing up in one spot, etc. Its happening almost every day now, whilst earlier in the year : late last it it would only occur after running over 5 miles, which was bad already.

Fitness seems to be deteriorating quickly... it just seems weird. I don’t think it’s psychological after being told of the results.

Perplexed and a bit confused...
