yes ive had a dvt bfore - my only symptom was suddenly feeling something in my leg that made it hard for me to walk. I had ad keg ache in the calf for a few days before hand. i too did not have any swelling or redness. I made a packed lunch, took a book and took myself off to casualty where they gave me a venogram and did blood tests. All the time the doctors were saying it wasnt classic dvt so they didnt think i had one. However, i had an ultrasound of my leg the next day and i did have one behind my knee.
Do yu have any of th risk factors?
