Deep pimples around liver area after eating coconut oil

Hello all,
Ive searched the forum and did not find an answer, so I'm hoping someone can help. I have been using cocnut oil as a face wash for about 3 months and it works wonderfully! I attempted to start taking 1-2 teaspoons daily before meals as suggested by quite a few people. I started to get painful deep pimples on the skin around my liver area which eventually spread throughout my whole back. They lasted until I stopped taking the oil about three weeks later. (I was trying to 'wait it out')
Any suggestions on how to handle this? How long should I expect this to last?

Thanks all! Have a great day!
