Tonight I noticed my ICD (11months old) has developed a lump at the top right corner as if it is being pushed further forward there! It's always been quite prominent especially along the upper part of it. I have it on my right side it was my choice as I'm a lefty and my right arm is restricted by arthritis so thought I might as well have it that side as I would never be able to raise that arm anyway! But apart from a nasty wound infection 6 weeks after surgery which is actually the exact spot this lump has appeared I have eventually got used to having a " mobile phone" lying under but extremely close to my skins surface! It's defiantly not infected but it did feel awkward this evening but it sometimes does as if it's moved slightly out of place but I've never had this rather alarming protrusion. I'm hoping it will have settled when I wake in the morning and it won't have ruptured through the skin! I'll phone the ICD clinic in the morning but it's an hour and a halfs drive to the hospital and parkings a nightmare, there's no point going to my GP as he admits he knows nothing about ICDs and says go to the specialists. Just wondered if any one out there has had an ICD misbehave in this way?
