I know your comment was from a little while ago, but I wanted to touch base with you, . What did the nurse who was helping you say? Unfortunately I can not speak to the specific situation you were in, but your confusion and worry about whether or not it went through is completely valid and understandable. Of course you want to make sure that the medication you're supposed to be getting you actually did get! I would check in with the nurse and ask if they have experience with the yellow thing going down but no pop. I hope you get some answers and reassurance! And please, if you're comfortable, let us know what you find out and how you're finding the Humira. Sending you gentle hugs. -- Warmly, Christine (Team Member)
