My husband has severe damage to his lymphatic system caused from inguinal hernia surgery. He has had multiple occurrences of life threatening cellulitis and will always be at risk for strep and cellulitis. Every time he has surgery he has a strep infection and cellulitis. Does anyone here have this problem or know anyone who does and what, if any, medication regimen they are on. My husband is on 500 mg bid of Pen VK and will continue to take this medication indefinitely. Thank you for any information.
