Suggest Remedy For Fluid At The Feet

Dear Dr. Agarwal, Last Sunday I had been fallen from the bike and there created a wound beneth my knee. The location has been swalloed with a reddish spot but not bleeding. That day I took a titenus injection and consulted with MBBS doctor, who suggested me for a 5 day Amoxicilin and Potassium Clauvanate Course alongwith Pain Killer and Betadine ointment. After using it for 5 days I found little improvement but nor remarkable one though doctor assured me it will be OK within 5 days. After that I consulted with another doctor who told that Amoxicilin is not perfect for this condition and suggested Cefuroxime Axetil Dispersible Tablets for 4 days with 2 tablet daily alongwith Chymoral Forte and ointment Mupirocin. After using this I found the would becoming dry but there fluid has started to gater at my feet resulting into problem in walking. Kindly advise what to do?? I am 45+ with no suger having medication of BP and is working in Office. Pl. note that I have attend Office due to some urgent work . Kindly advise suitably per return. awaiting for your reply
