Hi i am Dr Ahmed Aly
thanks for using healthcaremagic site ,
I had gone through your question and understand your concerns ..
Sometimes it happens that the edema or the inflammation goes down making swelling but that happens when you stands a lot or bending your knees while sitting thus causing less blood flow back to your heart from your venous flow .
I recommend elevating your ankle above your abdomen level as much as possible while taking your anti edematous drugs like alphintern tab 3 times daily before meals , NSAIDs painkillers like
advil tab or
aspirin , hot massages with topical gels , avoid standing and sitting for a long time , avoid bent knees , will be effective for now
if swelling persists i suggest further investigations like Doppler U/S on your venous system of your swelled leg for proper management .
