How To Reduce The Swelling And Pain Of An Amputated Toe?

Hello.... My boyfriend has had an amputation of the big toe on the left foot. The first one was about 2 months ago.... He was out sof work almost four straight weeks. The doctor finally cut him lose and he went back to work when he went back to work , he worked like 3 or 4 days and he got all kinds of pain, swelling and discharge the pain was unbearable. So, we went back to hospital and they admitted and went back in for a 2nd surgery and more infected tissue was amputated as well. He has worked one week and now he has lots of pain but no high blood pressure, some swelling but no heat in/around where the stitches were . By the way he is not diabetic either. He is 56 years old and had ostiomalytis a few years back and the third toe on the right foot. He never had all this much trouble with the first amputation. My real ? IS right now is he is off from work and it is swollen like I said no fever or hotness no discharge...... Is there anything he can to get some of this swelling out.... he has an appointment tomorrow so he does not want to go today.... the wait time in this particular office is horrendous. And of course if any of the other symptoms are present or he gets worse I will get him to the ER. thank you if you could just give me an answer about the swelling.
