My hamster is twitching/jumpy all night, has a lump under the forelimb skin, and unknown fluid at its mouth
Based on your description, the hamster is likely frightened or sick. Severe fright causes panic, loss of bowel control, refusal to eat or drink, and cowering; some show weakened heartbeat and breathing. The mouth fluid may be it cleaning its cheek pouches, or heatstroke in hot weather. If symptoms persist, see a vet to find the cause.

What Do Newborn Hamsters Eat? How to Care for Baby Hamsters
Newborn hamsters depend entirely on their mother's milk and are usually weaned at around four to five weeks of age. Once their eyes open you can introduce easily digestible hamster food, and by four weeks they should be separated from the mother to prevent stress and aggression. Avoid spicy foods and fruit pits, which can be toxic to hamsters.
