LDH was elevated

Hi all, I have been in remission for 14 months from Stage 4 Non Hodgkin’s DLBC. Went for my 3 month check up and my LDH was 266, 90-234 being the range. I’ve had a cold for a week and a half and have been taking a lot of aspirin and ibuprophen, also I had a few vodka, club sodas the night before, which I normally don’t do. No other symptoms. Dr thinks it’s all the above, still nervous though
