St Jude I believe was the one its been like 6 to 7 years ago sorry but I am pretty sure it was from them . Thank you for reading my story ❤️ well it was mainly I think doctor but the battery pack I was alergic to it they also think it's a posability it leaked or something not sure but anyway I had 3 different infections around the battery pack erea it was awful it leaked constantly threw bandages so just it was a blessing to get it out and the antibiotics work after all that .
