I underwent R_CHOP chemo therapy for non-Hodgkins follicular lymphoma.  I am now in remission (since Dec 2012. Since Jan I have been experiencing pain in my tailbone - like a dull bruise. Is this a side effect of the chemo or an indication of some other cancer?
Dear, hope you are doing well in your remission phase. It is very unlikely to have tailbone bone due to chemotherapy specially after one year of your remission phase. NonHodgkins Lymphoma recurs, but it is not associated with cocydynia (tail bone pain). Cocydynia occurs mostly due to local injury over that area. If it persists and bothering you consult with your family physician. You can take simple analgesic medication meanwhile.
