Hi, my name is suziwoozy! I had a complete knee replacement 5 weeks ago

Hi everyone. I'm new to this forum and hope everyone is recovering well. I had a complete knee replacement 5 weeks ago. I find I have a good day and a bad day. I only get about 4 hours sleep at night now due to the discomfort. Pain has now gone just discomfort and knee feels sore.  I seem to have alot of swelling on the inside and outer side of knee joint. Is this normal? I can now walk in doors without a stick if I havnt overdone things. Outside I can walk for 20 mins with a stick but can feel the knee swelling as I walk. Is this also normal? Thankyou for reading my message
