I agree, it will just take some time. Especially if she's got more than one in there. I would surely keep giving her warm baths, massaging her and giving her oil on both ends. Keep us posted!
Oh my goodness, she looks really uncomfortable. I'm sorry. You seem to be doing all the right things and yes, I would put her in a dark and quiet place where she can relax and stop producing eggs. I hope someone will come along with the million dollar answer!
