Cycling has been GREAT for SI joint and sinus problems
Don't know if anybody who'll be reading has SI joint dysfunction, but it's pretty common so I wanted to say that cycling has really helped me out a lot. I (and lots of other people) have a problem with my hips and pelvis getting out of alignment and that messes up the SI joint and causes severe back pain. When my back goes out, it stays out. The chiropractor hasn't been able to help me or anything and it has lasted for several months at a time in the past. When I get on my bike and start riding, by the time I get to mile 5, something amazing happens. I get a pain in my hip joint - like the ball of my femur wants to pop right out of the socket. The pain gets more intense, then I feel a little "pop" and amazing relief. My back feels great again, and it stays great until I lift something heavy and get everything all out of whack again. I think everybody with SI joint dysfunction should try cycling - it's a miracle cure. It has worked for me every single time since I discovered it.
I also have chronic sinus problems and get frequent sinus headaches. My sinuses don't usually drain on their own - they just get more and more plugged until it feels like my head's going to explode and I finally take some medication. I hate taking medication. I was amazed when I started riding my road bike and had to start bringing a handkerchief. It will probably sound gross to people without the same problem - but I am so grateful when I have to blow my nose. I think it's the position and the vibration. Going over railroad tracks and bumps is intensely painful when my sinuses are clogged. I cringe and practically cry at first, but pretty soon the ol' sinuses open up and the snot just starts flowing like a faucet! :o
Just thought I'd share.
