Hi, welcome to our site. I am Dr Saumya Mittal, MD.
Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query
To me it sounds like you have a source of infection in the leg and the swelling in the leg is secondary to the infection, something called as
cellulitis.
Now I think what you may need is a
blood culture and swab culture and then antibiotics. Only the resolution of the infection may actually bring down the swelling
I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further.
I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you.
Please do understand that some details could be extracted from a detailed history and examination.
Please feel free to ask another query. I would be glad to help you. Looking forward to your return query with the details asked so that I can help you further.
(If the answer has helped you, please indicate this)
Best of luck.
