Hi my Dad is 71 and about 10 months ago he pulled his groin! Immediately after his leg swelled! After 2 months he saw his gp who sent him for an ultrasound! No tear noted but his lymph node in his groin was slightly swollen! Fast forward to now and his leg remains swollen! Just one leg! Pain in the groin has reduced but still there in some movements! He has anothe ultrasound this week and nothing has changed! GP checked under arms and neck and no other glands were swollen! No other symptoms other than the swollen leg! Any advice? Thanks x
