Jett 130 and Zero and sit bone LUMP

[maillotpois]

Thanks, guys.

What was really weird today was I saw down hard at the wrong angle on that lump once, and got a shooting pain in my butt/leg just as though I had hit my funny bone! So now I have a funny bone in my butt!!!

Is that like a bunion... on your sit bone?

Could be muscular, could be a swollen lymph node, could be a benign fatty tumor (lipoma)... lots of stuff. Whatever the lump is, it sounds like it's aggravating your sciatic nerve. Sciatica caused by impingement on the nerve from muscular tightness is known as piriformis syndrome. Some things for you to look into...

Hmm. Interesting - thanks!

No solution for the lump, but a thought on your old saddle (although I loved my Jetts!) Saddles do wear out. The cushioning shifts and the shell gets brittle. So, you might want to go back to your original favorite.

Well, I've "seen" (felt, actually) a lump at the insertion (aka sit bone) of the hamstring on a couple patients. Both were athletes, one was an endurance runner.

They were considered high hamstring strains, most likely due to an imbalance of effort between the medial and lateral hamstrings.

Both these patients were women (seems to be more a girl thing) and both were solved by treating the FEET and working on general leg stabilization exercises. Overpronation caused the hammies to fire up funny in an attempt to stabilize the leg/pelvis.

If you already wear orthotics, you might want to call your orthotist and see if your orthotics need to be adjusted.

Otherwise, ask your doc what she/he thinks. Maybe a medial wedge on the underside of your regular insoles would help. The doc would be able determine that.

Wow, Knot. Thanks!

I do pronate, and used to have orthotics when I ran (before I wised up). Maybe I should try to find them and put them in my cycling shoes....

Could that impinge the sciatic nerve as Dianayla suggested, leading to that "funny bone" business I felt?

If the hammies are strained, they could be kicking off all kinds of compensatory tightness and other exciting goodies. (including referred pain)

A few piriformis stretches could be good, as could some gentle hamstring stretches.

Since a cyclist weightbears on the forefoot, and most orthotics are designed for hindfoot correction first, your running orthotics might not be adequate. But they certainly couldn't hurt to try in the bike shoes! If they don't seem to help with the pain (the lump will take a while) ask your orthotist to check you for a forefoot medial wedge for biking. (make sure to check BOTH feet to see if they need medial wedges!)
