Really worried about MrsC.
She's had fluey illness for a few weeks.
Separate from that, her ankles have swollen up and her calves are swollen and rigid (she's not prone to getting puffy swellings on legs). It's not like just common fluid retention, on one leg her whole calf muscles is swollen and absolutely rigid.
A suggested caused (yes, I know, stop looking at drgoogle) is obstructed blood flow, with 'masses in pelvis' being a cause (e.g. pregnancy). MrsC has a large (benign) mass in her pelvis. She won't go to the doctor.
