you might check the alignment on your seat nose...? It has happened to me (evidently while getting the bike down off the hook or maneuvering around rearview car windows in the garage) but somehow knocked my seat alignment slightly off & I felt something strangely straining in my leg during the ride. At the end I happened to look at the seat & it was a few mm. off-center. But then again I may be imagining that my bilateral symmetry is sufficiently perfect to cause something like that to make a difference. Now I check it almost every time I get on the bike (just another obsessive checkpoint of comfort).
