Ok I have no idea about the infusion and work but I will say your health is number 1. I have had to take off school and work in the past for my recovery. It was hard but I had to remind myself and now you that you have to look long term. Its better to take a little time off now but in the long run have a healthy and more fufilled life.Sometimes rushing back is not good for the health mentally or physically too. If your able that is great but the most important job you have is to take care of you now. I'm sorry the pain is getting worse but good luck on Thurs.
