Within last few months (it's gotten worse) her eyes opposite dilate(?), and she starts making this 'sucking' sound. As soon as I stop she licks my hand and then acts like she's trying to get fleas off me (biting on the skin but not breaking it). She doesn't have fleas btw. Not her normal behavior before about 3 months ago. She also seems to have lumps under her skin in that area (just in front of her tail). Not sure what to do or what it might be. Vets are really expensive here and I don't want to scare her or put her thru a lot of pain if I don't need to...
