"I'm still a young guy.. my legs shouldn't lose circulation until I hit late 30's"
People are getting heart attacks at younger and younger ages bud.
" need to fix this problem because it seems like blood is pooling in my feet"
What's wrong with you? Why are you afraid to see the Doctor? What are you going to do wait til it becomes gangrene and then run to the doctor so they can lop it off?
"this could mean heart attacks"
No. Worse it can spell infection, Gangrene, loss of affected limbs or even death.
That's what happens when injuries are not properly treated.
Don't worry about money. Go to the ER if you are not insured.
