How Can Foot Itching Be Treated?

Hai I am 35 years old female, On Monday while traveling from Mantralaya, they had stopped for tea and coffee at that time there was no light and it was completely dark in the morning and without noticing I fell in a pit, which consisted of mash, very bad smelly mash, it might be either a drainage or waste food storage, at that time I foot got caught into it and I pulled my leg. From that day I have some itching in the foot area.
