March is DVT awareness month.
I am a survivor of DVT.
"DVT occurs when a blood clot forms in a deep vein, usually in the lower limbs. A complication of DVT, pulmonary embolism, can occur when a fragment of a blood clot breaks loose from the wall of the vein and migrates to the lungs, where it blocks a pulmonary artery or one of its branches." - Melanie Bloom
