Hey, I would like to ask what causes a few lumps to appear significantly after I flexed my legs? Those lumps are not painful and not movable.
Here a picture of the lumps when I flexed my leg:

Probably nothing to worry, they look like a cluster of cysts. But don't be nonchalant about them, there is a SMALL chance they could be malignant, so go have the doc remove them and send them to the lab!
