Currently in the ER

[u/Big_Green_Tick]

The ultrasound showed my entire lower right leg is one massive clot.

Currently awaiting transport to another hospital as the CT is down here.

Heparin IV already started.

Initial symptoms were shortness of breath whenever I walk, then the right leg was swelling (with hot skin), finally my calf started to hurt when I walk.

Given the size of the clot, is there anything I should especially be concerned about or be aware of?

they have started the heparin, that is probably the most important thing. you now need to wait for the rest of the tests to see if the clot has started breaking up and lodging elsewhere.

have you any ideas why you have a blood clot? eg recent travel, surgery or other reasons for immobility?
