Sprain near ankle. See physiotherapist?

Hello doctor, I have sprained my ankle,while walking I just felt , later I realised that I twisted my ankle. That night it was swollen . .I did applied icepacks , raised it and tied crape bandage. .I thought it will be okay in few days. doc told me that it's ligament sprain. .and in a week I will be fine. .but it's been a week now. .I am having calcium tablet everyday as prescribed and without crape bandgae I can walk fine but not like normal. I have been asked to keep crape bandgae for two weeks more. .while climbing steps it's not an issue. .but while getting down Its a bit difficult. I have been asked to treat it with warm water. I really have urgent appointment next month and don't want to delay it . That's y this concern. Do I need to see physiotherapist ??
