Cyst on Sesamoid bone

I had an MRI due to a fibrous non-union of an avulsion fracture of the 5th metatarsal. I got the MRI report and in addition to the fibrous non-union I also had a cyst on the tibial sesamoid bone. I had never heard of a sesamoid bone before and never felt any pain. Two days after I got the MRI report I had to drive 4 hours away from my house. A couple hours into the drive my drive the pad of my big toe began hurting. Because of the fracture I have been walking on my heal and my big toe keeping my weight off the outside of my foot. I saw a podiatrist about the fracture, which needs surgery, and asked about the sesamoid cyst. He said it was probably something I've had for sometime and I've aggravated it with my gait. He said the only way to fix it was to remove it only when it became painful enough to warrant an operation.
It would be in your best interest to see a podiatrist about this problem. It's hard to find someone with the same injuries as you and only a podiatrist really knows how to handle your unique problem. Good luck
