Nice day, calm but heavy swell and cold. I feel fine in the morning till dinner time. when I went to the lav. Then the pain took me again, terribly so. In agony, could not ease it standing. laying or sitting. Glad it did not come on before dinner, for a lovely New Year meal was served from the galley. Twice I went to bed , got up again back to work, could not let my mate do it all . Eventually, after tea was served , I had to go. I just left the galley saying nothing and went to bed but not to ease. I was holding myself when the steward came in and saw me. He said I am to see a Doc.
