In February 2011, I had a neurostimulator implanted at the base of my skull to help relieve an electrical shock type pain along my greater occipital nerve. Everything was going fairly well with the surgery until about two months ago when I got a very bad upper respiratory infection. Since then, some of the occipital lymph nodes have started swelling and I can't turn the device on. Obviously, if I can't turn the device on, I'm not getting relief from the occipital neuralgia. If anyone out there has a neurostimulator, have you experienced swelling over the incision site 3 months after the actual surgery? I didn't have this type of swelling immediately following the surgery, so I don't know why it won't go away now. I've been on several rounds of antibiotics and the swelling won't go down. I'm looking for other suggestions. Thanks.
