If medical advice/intervention is needed, would the patient's two friends be encouraged to warm/cool the patient's body (ice, etc, to bring the fever down - or might he develop chills as a result), with relation to the fever, in this instance? Would the delirium be treated separately, or at all? What topical treatment to the wound itself would be necessary? Story is set in the present, in a large US city, and the characters could potentially have access to information via the internet, and general over-the-counter remedies and medical supplies, if that helps.
Thank you for any help you can provide, with regards to any of these questions. :)
