I will try and make this brief and I apologize if these questions have been answered before.

After about 5 years of riding bikes in the city, I finally made the switch to a fixed Bianchi Pista and I've been experiencing some weird pains and I'm wondering if any are common or will improve over time..

-Ankle pain: Besides cycling I also skate a lot and have done both for years but, since going fixed my ankle has been aching 24/7. The pain isn't really intense, just annoying. I just don't want to do any permanent damage. I am almost positive my seat height is fine, I use toe straps and the stock 48/16 gearing. Is this normal? Are my straps not tight enough? It is hard for me to get my feet in and out while riding any tighter. I kinda feel like maybe I'm doing too much work, especially pulling, with that same foot.

-Shin splints(?): I am not sure if that is what it is but, there is this constant shooting pain in my shin (same leg) anytime I am putting weight on it. Again, not that bad but, I'm just worried about long-term issues..

-Chest pain: While trying to learn to skid (I have a brake, just experimenting) I started getting crazy chest pains. I feel like I am fairly limber and healthy and have never gotten this any other way. Obviously, I don't have to skid but, it's fun sometimes.

Are any of these symptoms normal when starting fixed? I am fairly concerned because I already have some knee and lower back issues, not to mention my ankles are kinda ****ed from skateboarding..

I have kinda jumped right into it, going on extended rides right off the bat.. I am really hoping you will all tell me that all these symptoms are normal and I will gain strength in all of the affected areas.

Please?

Thanks.
