It's been 2 months since I treated it 3 times at the hospital, but it's still as hard as a rock. I heard there's a high-frequency machine that can be used at home to remove bone spurs, but I'm worried because it costs 80,000 won, will it be of no use? I said I try my best to use warm compresses, but my stomach looks weird and I'm really upset. I think the world will be better if I get rid of this idiot.
