I iced my knee a lot on Saturday night and throughout Sunday. On Sunday evening the pain was so bad that we decided to go to the doctor on Monday.
We went to the doctor, they took an x-ray and told me to ice it and eat ibuprofen and wait for the x-ray results.
The results came already on Monday night and they tell that there are no broken bones in my knee (which I could kind of guess even without the x-ray bc the pain was not so bad). They told me to ice it daily and see if it gets better.
