Hi, I am so sorry to hear about your mother. I don't know if I can offer any help, or even if what I am experiencing is the same thing. My pain is on my right side, right at the top center of my right rib. It is not a burning or aching pain, it is more of a 'charlie horse' which comes and goes and last from 2 mins to hours. It is very painful as I cannot seem to sit, stand or lay down when this is 'spasming'. I am going to the oncologist in 2 weeks for reg check up. At that time I will also mention this pain to him.
I have not heard of anyone else having his pain before and I pray it is NOT cancer related.
Please, please, please, keep me posted.
Lilie
