Maybe. Have you had the pain for the full 500 miles - were those hilly, what were the weather conditions like (Static trainers don't really count towards mileage
...how long have you spent on it)?
Not all physios are created equal
Did you stop running to relieve the shin splints? Did you get a gait analysis, the right trainers?
Spent 6 hours on the trainer. Hasn't been as intense so far as the real rides (Sweet spot base 1, for anyone familiar with Trainer Road), but I was experiencing the sides/tops of the thighs aching before the trainer, and when I first went on the trainer. Raising the saddle got rid of it, but made the reach worse and seems to have caused the trouble with the backs of the thighs as it's not something I've experienced before. My thoughts are that the saddle going back as a result of the post going up is causing it, as it feels like the crank is below and in front of me. I feel stretched on the reach too and as I said before the saddle is as far forward as it'll go.
The shin splints go back years; in my early twenties I broke every rule in the book when I took up running - inappropriate footwear, no warm ups, tarmac, up hills. Then tried to run through it thinking it was just something I needed to get used to. When physical bruising appeared up the shins I stopped. Never really went away (always felt running up stairs etc) so before buying the bike last year went to the GP and was sent to physio and podiatry. Had my walk & jog looked at, acupuncture & physio. Turned out I had a bit of a funny walk that I didn't know about. They thought it may have been neurological, but it was barely noticeable so didn't take it any further. To try and straighten it out they gave me some custom made insoles, which hurt like hell and wrecked my shoes. Stuck with them, got used to them, got discharged, wore them out and realised they did naff all anyway, so never went back.
As I was going through the appointments I mentioned I needed exercise and so took up cycling on the basis that there was no/low impact. Physio thought it a good idea but recommended I didn't clip in/pull so as not to aggravate the shin splints. Cycled for a while and broke the rules/clipped in, because I kept slipping off the pedals. Funnily enough, my walked straightened out (I'm sure the cleats had something to do with it) and I had nil issues with the shins.
Not sure if relevant but I also have varicose veins in both legs (far worse in the left than the right), with which I regularly get some pretty nasty aching (particularly if driving a long way for work). Local NHS trust wanted to perform stripping operation, which I refused until they start offering laser treatment due to it being ineffective/from the stone age and not being able to afford six weeks off work. Fear of that getting worse is what's driving me to exercise. When they play up, the left one hurts behind the thigh, just above the knee. It's not the same as last night though.
