Hello, I have just been diagnosed with oral cancer and am waiting for further tests to establish the treatment needed. I have been reading loads but can't seem to find the answer........my ear is very painful and I can actually feel something in it (not to the touch but sense wise). I have also been experiencing some giddiness, not daily but at least 3 times in a week or so. Is this common with oral cancer and if so why? Any help or thoughts would be much appreciated.
