Some one please help

[Jammatart]

Could some one please give me there advise on what to do with my pet green tree frog cena. When I first found him he was lathargic. He is still eating but keeps growing in size I've done a lot of research I think it could be edema or possibly a blocked bowl. I've tried warm water baths but still nothing I don't have any vets near by and need some assistance. I watched a you tube video with a lady syringing blue liquid out of a swollen frog with the same symptoms. I'm willing to do this if it means saving his life. I have attached some photos from when I found him in this state and 6 days later. He is a battler and I want to know I've done everything I possibly can to help him.
