sounds like a Baker's cyste (not sure how you write it in English)
yes bakers cyst - i have been recently diagnosed with this about 10 weeks ago and have gone a treatment of antiinflamintries to reduce the pain which happens around the 80-100km mark in saddle.
Alternate medicine is the all good famous "Stop what you are doing that agravates it"
I concur it's a cyst. Could go away on its own, could linger for a while.
I have one the size of a golf ball in my hamstring. Been there for a year now and we continue to monitor it when I go in for checkups and blood work. Surgery is an option, but not a necessity.
Just keep your eyes on it.
