I have multiple fibromas in the arch of my right foot (2 visible, some not visible) and none in my left foot. For years, even a few years before my first fibroma was discovered, I have experienced sudden cramps in one foot or the other that sometimes spread to my legs. About 85% of the time, it is in the foot with the visible fibromas. They only happen in the evenings, and sometimes they wake me up in the middle of the night.

They make my toes want to curl, and I have to grab them and bend them backward when I feel the cramp coming on. Occasionally, that makes it go away. If they get worse, the only thing that helps is extreme heat, but I can't walk so someone has to help or I have to crawl to the bathroom and get in the shower. (I keep a heating pad near my bed, but when the cramps are severe, it takes too long to heat up.)

Some triggers are high heels (I gave up wearing them), a lot of driving in start and stop traffic, walking a lot, standing barefoot on cold floors, dehydration, and airplanes (due to dehydration according to my doctor). The airplane cramps are usually in my shins, though, not my feet.

Although the cramps started years before I was diabetic, they definitely happen more when my blood sugar is uncontrolled, so I had assumed it might be a diabetic thing, but after reading the forum, I am wondering if the cramps could result from Lederhose disease.

I also get the weird episodes of burning tingling feet some had described, which I had assumed was neuropathy but am now wondering if it might be the Lederhose. Or maybe my diabetes and Lederhose are working together somehow, given that the disease is more common in diabetics. I found that ibuprofen makes the burning/tingling in my feet go away (it feels like an icy burning, if that makes sense).

Does anyone else have sudden foot/leg cramps and, if so, do you also have diabetes or is it definitely the Lederhose? How do you manage it? Is there anything one can take that would prevent it? I have had it happen while driving at night, and have had to pull over!

YES!!! Me too.
I constantly have severe cramps. Triggers are as little as... Bicycling... Stretching.. Walking.... I have different cramps at the same time. It definitively started with LD.
Just last night I woke up in the night with cramps in the toes of the two feet, in the arch on the left foot, and as i was trying to stretch to have them go away, it started it the leg.
Interesting that you relate it to diabetes. I somehow think that all this is related, sugar level, liver, metabolism of calcium, etc. Also, it could be that as the fibrosis expands and glues the tissues together, the foot and toes have less flexibility and range of motion to do what they used to do. Just this might trigger cramps I guess.

I too have cysts and fibroadenomas in the breasts.
I guess the moral is : take care of our feet just as much as we take care of our hands.
I love walking barefoot or in flip flops. I must adapt I guess.

I am not certain I have Ledderhosen but I certainly have Dupuytren. I left hand ring finger and a pronounced tendency to curve inward. Like my lest hand my right foot seems to be drawing my ofter toes inward. I too suffer from night time cramping in my right lower leg and foot. Sudden cramping events which cause me to catapult out of bed seeking relief. Like any cramp extending the muscle against the direction of the contraction is my only relief. Stretching my toes seems to delay the time of the events ones. Shins cramps (very painful and difficult to relax it)- lower leg, (calf to ankle) are large muscle contraction is easily identified and often delayed/ stopped if caught very early in contraction cycle or the foot. Which often accompanies the others, I believe 'pointing my toes' during sleep, due to the weight of the covers may exacerbate this 'curling of the toes' and is the initiator of all the cramping behaviors. Anyone experience similar things?
