Just thought I'd post here rather than a new thread. I caved in the end, was seeing a physio, he could see one hand is resting against my hip whilst the other is floating in the air (when stood) which shows one side of my pelvis is higher than the other. Leg length seems to be about 1.2cm different (left shorter).
I've gone to see a chiropractor and he made some adjustments (a hell of a lot of cracking occurred), he told me this is temporary (probably worn off by now) and I'm awaiting on what he details based on his assessment are, he'll then give me a plan of action to help me reduce the symptom.
In the meantime I try get out 2 to 3 times a week, I can only manage 20 miles, maybe 30-40 if I'm really lucky, always in lots of pain by the end of it, a lot slower as I've gained 2 stone since a year ago. It's like a train wreck cycling life just hope I can recover, especially now juggling fitness with a baby son and angry girlfriend.
