Hi i am Dr Ahmed Aly
thanks for using HealthcareMagic site ,
I had gone through your question and understand your concerns ..
In my opinion i think she may have a kind of vascular insufficiency due to low venous return . this could be due to standing for a long time ,sitting , bending knees , bad sleeping postures .
She may use ant inflammatory tabs , elevate her feet above a pillow while relaxation , wear compression stockings , hot massages with topical gels , 1 daily
aspirin pill after breakfast will be helpful for most of cases .
If swelling increases or persists i suggest Doppler U/S to rule any
vascular injury and visit her physician for proper evaluation and management .

Any further clarifications feel free to ask.
