Question: The skin around my stitches is black. This was a very bad fall and a 7" laceration under the knee cap. I can't tell if this is dried blood or something worse. It is slightly warm. I have no feeling there so that's all I can distinguish.

Brief Answer: Details below Detailed Answer: Hello Thanks for the follow up. Here is the explanation for your condition. 1. Warmth at the wound site is due to inflammation, as the injury is recent. Its good you are taking antibiotic,soon you will be relieved. 2.Pigmentation is due to collection of hemosiderin ( blood pigment). This will take around 3 months to disappear. 3.Numbness is due to injury to cutaneous nerves. These nerves regenerate very slowly and will require at least an year to regenerate. Let me know if you have any other doubts, Thank you

My father, age 78, is in excellent health and only takes medication for hypercholesterolemia (low 200 s). He recently started Erythromycin for head and chest congestion and sore throat. After taking this for a few days he had blood blisters erupt in his scalp and ears. His head felt a lot of pressure and he was worried he might be having a stroke. His neck and head were stiff with some numbness in his right arm. He DC d the antibiotic and went to his doctor, who placed him on Prednisone. Now he is a little groggy and isn t feeling well so he stopped the Prednisone. He sounds weak and we aren t sure why he was put on the Prednisone. My question is - why take Prednisone if the blisters are drying up? What is the benefit versus the risks?
