Usually a bike shoe/cleat fit starts with the front of the cleat level with the big toe. If still numb - move the cleat back until numbness stops happening. Or so said the fabulous bloke who did my bike fit.
Not exactly a medical opinion but is sounds very similar to a severe 'bout' of shin splints I had once. I am one of those folks who got the dreaded shin splints when I started running (or walked around in hard high heels too often) - right down the front of my shins - the usual place. I ran through them, toughened up and thought the issue was just a matter of getting used to it. A few years into my running career I did a few too many races followed straight away with hard speed session (yes I know better!). The pain I had made me almost vomit. Sharp, nerve pain that felt like there was exposed nerves wrapped down and under the bone in my leg and back into the achilles. i.e. Like the leg bone was right on top of a nerve. So, not exactly how you describe but certainly from front to back and to lower part of the calf. It did turn out to be shin spints and I got physio, retrained myself to run mid-foot and did lots of yoga. Not the perfect answer to your problem as I had an obvious mechanical issue with my running style that I could change and that solved things (only took a year or so )
One place to start would be a better/different physio. I have a guy I go to that doesn't give up till he finds the answer but over the years have seen many who have shrugged their shoulders and said 'don't know - rest and see'. A good physio is worth their weight in gold.
I wore them at outlaw. At least I am assuming it was the same thing. I had Compressport white arm warmers/coolers with 'cooling technology'.. erm or something like that.
I wore them because I had a serious problem with my skin at the time - lots of steroid cream on them and very red itchy and sore - so had no choice but to keep the sun off them at all cost. What I found was that dousing them with cold water at the water stops worked a treat and kept me cooler than expected throughout the race. My husband copied me (no probs with his skin but he liked the idea) and also reckoned they kept his arms cooler. I did wear them under my wetsuit and so started off on the bike lovely and cold. I have to say that my photos look rubbish right enough as I have lovely bulges out the top of the white arm things... but hey ho.
However, hopefully all of the media attention will help to highlight the seriousness of depression, how it can affect anyone - even someone who appears to have everything, and who from the outside may have been a funny, intelligent person - and encourage people who need it to seek help. And those of us who are in a position to make a difference to someone's life may do something that will help prevent someone we do know and care about ending up in the same situation.
Well said Nessie. This was my first thought also. I have known so many people whose lives have been touched with mental health issues and unfortunately I have also seen how difficult it is for some people to understand or empathise.
