Up until a month ago, I only ever biked for my commute, about 6 miles roundtrip. Recently, I found that I enjoyed longer rides through the hills around my home. I started doing about 20-25 miles, 5 days a week, for the last month or so.

About a week ago at work, I noticed my shins felt all pins and needles. Later that day on the bike home, I noticed that both of my legs were getting pins and needles, and going a bit numb. After that day I stopped biking altogether, but the pins and needles persist in my feet, legs, hips, and low back pretty much whenever I sit or lay down.

I'm a bit concerned that it came on so suddenly in both legs, and that the symptoms have not decreased after taking time off. It's almost certainly a sciatic nerve problem, I imagine from my cheap bicycle seat, or bad positioning. I am only 23, so I would doubt it is a spine problem.

Has anyone encountered tingling that persists many days after biking has stopped? If so, how long did it take to recover? It is very annoying, and makes it hard to sleep.

I've scheduled an appointment with a neurologist, but it is not for several days.

Thanks for any insight!
