Is the swelling limited to the ankle or does it include the calf of the leg?
If it should include the calf of the leg then i would worry about a possible clot in the leg or DVT (deep vein thrombosis). This would need to be evaluated tonight if you believe that this is a piossibility.
If it is limited to the ankle >>which side is swollen?
It is possible that you could have sprained the ankle and niot realized it at the time.
The swelling and pain can worsen over several hours. (sort of like a case of whiplash >>it can hurt much worse the next day)
it is moving up the leg and it is hurting more and more and now I can hardly walk, it started very small ankle pain I am freaked out
Since it is progressing up the leg and it hurts to bear weight I would advise you to play it safe and go to the ER and have this checked out further.
I would worry about a potential DVT as a possible cause.
This is just one possible cause but if this is the cause it is quite serious and needs to be started on treatment right away.
what is dvt I cannot drive myself and have no one to take me, ok to do in am
No you can call 911 for an ambulance. A DVT is a deep vein thrombosis which is a clot of one of the deep veins of the leg. IF this is the cause then it can lead to a clot traveling to your lung and this can be fatal!
A possible DVT is an acceptable reason to call for an ambulance to help you get to the hospital.
