It is possible but it is also possible that it has nothing whatsoever to do with lymphoma. There are a number of reasons that this could be happening...some more serious than others. To rid yourself of this concern, see your doctor. Worry never cured anything. If it should turn out that you do have a serious problem the best thing you can do for yourself is to get treated ASAP and the only way to do that is to see your doctor ASAP.
