Hi, i have been having a throbbing head for the last few weeks, since i had my final docetaxel and 3rd herceptin together and it got worse after my 4th herceptin on its own just over 2 weeks ago. It is not like a headache but a constant throbbing at the back of the head. I have tried various painkillers, i have seen my onc, had blood test and CT scan all ok, now I am waiting for Mri in just over a week's time. I have tried steriods also but they don't seem to work, my last appointmenta with onc, she suggested that it may be the herceptin but cannot be 100% sure. Has anyone else experienced this at all? I cannot be the only one out there who is having this throbbing head!
