Thanks for your query!
You do not seem to be having any signs or symptoms of Hodgkins disease. Increased sensitivity to alcohol can occur if you are allergic to certain contents in the alcohol or also if you are having a liver dysfunction. When you where on roaccutane, where you also taking alcohol?? As roaccutane taken during alcohol consumption leads to liver dysfunction which leads to intolerance to alcohol and also the itchy skin you specified. I would suggest you abstain yourself from alcohol.
Hodgkins disease apart from intolerance to alcohol also causes mainly enlargement of lymph nodes, night sweats, loss of weight, enlargement of your spleen and liver. None of these have shown up, therefore there is no need to be worried.
I suggest you get liver function tests done and also avoid alcohol consumption.
Hope this helps. Please feel free to ask follow-up questions.
