Yes, please list symptoms, include a photograph of tortoise and include enclosure.
We cannot offer advice if we don't know what is wrong. [SMILING FACE WITH SMILING EYES]
But general "emergency tortoise first aid" is
1) warm water soaks, 30 minutes.
2) increase heat and humidity by ~10 (10° and 10% is a good start)
3) baby food soak once or twice a daily over water soaks if possible.
Mix 1 jar babyfood:1 cup pedialyte:1cup water. Check often and keep temp up, it will drink the mixture and a sort nutrients thru cloaca.
