Worried I might have a blood clot

I work on a hotel and all of a sudden I start feeling some pain in my leg going through the tight to the foot.
It gets worst if I “close” my foot. I felt better in the next morning but it came back soon after. It’s a pain inside the leg almost like a vein and altough its not extreme it’s still bad specially cause its making me worried. I dont notice anything swollen or red.

Should I be worried?

You obviously are worried or you would not be searching about DVT and posting on the forum. You should get it checked out, even if its just for your own peace of mind. If it is a DVT the sooner you receive treatment the better. Fingers crossed its not and let us know how you get on.
