I think I've got a blocked vein in my leg after fracturing a bone in my foot 3 months ago.
JA: What are all your symptoms? Have you talked to a doctor about the fracture?
Customer: I went to the minor injuries unit several times. No treatment was suggested for the fractured metatarsal, just rest, which is OK bcause over 3 months this has healed. However, I noticed the swelling was not going away. Then lasst week I started getting pain. To cut to the quick, online diagnosis suggests I have 'superficial thrombophlebitis of my lower leg'. It suggested I get immediate help.Should i go to A&E or back to the minor injuries unit?
JA: The Doctor will be able to answer that. Have you seen a doctor about the fracture?
Customer: No.
JA: Thank you so much for your time. Finally, is there anything else in your medical history you think the Doctor should know?
Customer: No, I am generally healthy. The vein that is giving me problems was slightly varicose though, a bit 'knotty'.
