On road rides 45 mins into the ride my left hamstring right under my butt hurts. I change positions and pedal standing it helps some until I sit down. Further into the ride my toes become numb. But here’s the weird thing on my down stroke my leg is ok…. On the up stroke is when I feel the pain and numb feel. Should I get a wider seat?

Thanks

Much wider, get a recumbent. http://www.bikeroute.com/Recumbents/BentMedBenefits.php

Check out http://www.bentrideronline.com/ for great reading, education and reviews on recumbent bikes.

I gave up my road bike in 1995 and have never looked back. Keep your mountain bike, they rule in the dirt. I could give you all the recommnedations about seat adustments, making sure you adjust to the length of your left leg, but(t) the bottom line will not change much. The narrow bicyle seat is compressing your siatic nerve. Wider seat may help temporarily but you will still have undue weight in an area that was not anitomically designed to bear weight. The recumbent seat completely changes your weight distribution and there is no fence rail riding like on a conventional bicycle seat.

Thanks,

Thanks DOC, I took 2 days off the area under my butt is still somewhat tender would ice or heat or both help with recovery. Would this also explain my lower leg pain and muscle locking up. What else can I do for a workout.

Ice application will help the muscle but if it nerve compression, ice application may make matters worse by further impeding blood flow to the nerve so go with warm soaks and range of motion exercises. Go to a gym where there is a recumbent exercise bike and do some easy low load spinnings. This will allow you to work your muscle and joints without undue stress and it will take the compression off of the nerve that is being compressed. If this does not relieve your discomfort, visit with your doctor. There could be something more going on such as a disc herniation or a skeletal problem with the spinal vertebra compressing the nerve.

In regards to your upright road bicycle, have your seat fore aft position and seat height evaluated by a bike shop that does "Bike Fit" measurements and adjustments. You may need to go with a wider pedal stance or wider crank "Q-factor" to keep from compressing your sciatic nerve. Saddles are a tough recommendation as one saddle that does well with one rider's anatomy may not do well with another rider's anatomy. It is often a ride by trial assessment.

In regards to using anti-inflammatory medications like Motrin or Alleve, you may be best served by stearing away from them as they impede blood vessel formation which is involved in the healing process. You may just want to go with acetaminophen (Tylenol) alone if you need something for the aches.

Thanks,
