How Long Does It Take To Walk After Broken Mallelous?

Hello I m looking for some Orthopedic help . I ve broken my lateral malleolus a month and a half ago and just got rid of the plaster cast yesterday . I ve been wearing just a gauze since then but I couldn t walk yesterday . Today , I tried my best to and sort of did somehow but now the entire leg hurts a lot from the knee down . Maybe it s because I m overweight . And now , I have fever . I had two Paracetamols , but it didn t help . As a result I ve just replaced the gauze with a weight bearing brace and the walking is a little bit easier . Although I don t know if I should continue the walking for a while . It s just that I ve been missing out on my classes and exams in medical school for more than a month and so , I want to start going there . But , I m not sure if that s the best idea for now . Could you please tell me if I should start walking or take more rest for a while ? If no , then how long might it take for me to get back on my feet again ? And also should I take physiotherapy ? If so , then for how long ? Please help me out . Thank you
