Hi,
How are you? Do you still experience your symptoms? Deep vein thrombosis usually present with pain and swelling, warmth over the affected area, and changes in the skin color, such as turning pale, red or blue. To determine if it is DVT or not, direct clinical examination and diagnostic tests such as ultrasound, blood tests, venography and CT or MRI scans may be done. The pain could also be due to musculoskeletal issues especially if you were swimming prior to the pain. If it persists, have this checked by your doctor for proper evaluation. Take care and do keep us posted.
I don't think you have DVT! superficial thrombophlebitis. Superficial thrombosis affects only a localized area thus, the symptoms are only present in the local area of the body. It cannot cause pulmonary embolism thus, deep venous thrombosis is more dangerous than superficial thrombosis.
