It can be a vein thrombosis of the leg.
I am Dr.Rovena.
I had gone through your query and understand your concern.
Leg swelling, redness
, and pain may be indicators of a blood clot and should not be ignored. These symptoms may be due to other causes (for example, cellulitis
or infection), but it may be difficult to make the diagnosis without seeking medical advice
As you described it I can think only of two possible diagnosis:
-One is Superficial Vein
Thrombosis which is a condition in which blood clots
are formed in the superficial vein system.Most often occur due to trauma to the vein which causes a small blood clot to form. Inflammation of the vein and surrounding skin causes the symptoms of any other type of inflammation including : redness,warmth,tenderness,and swelling.
Often the affected vein can be palpated (felt) as a firm, thickened cord.
-Second possibility is Deep Vein Thrombosis
which is the condition when blood clots are formed in deep vein system. The symptoms of deep vein thrombosis are related to obstruction of blood returning to the heart and causing a backup of blood in the leg. Classically, symptoms include:pain,swelling,warmth, and redness.
Not all of these symptoms have to occur; one, all, or none may be present with a deep vein thrombosis. The symptoms may mimic an infection or cellulitis of the leg.
Since this both conditions need medical attention I suggest to take her to hospital as soon as possible to get the right diagnoses and treatment.
Hope I was able to help you.If you have further questions please feel free to write me,I will be happy to answer.
