So sorry she is having these problems. Drinking and urinating more can be a sign of kidney disease, Cushing's disease, diabetes, Addison's disease, infections, thyroid disease, etc. The only way to know the cause is to have a vet run some bloodwork and a urinalysis. The lump could be a cyst, infection, benign or cancerous mass. A needle aspirate or biopsy may be necessary to diagnose. She really needs to be examined by a vet. Try to find a low cost clinic in your area or a vet that would take a payment plan. You could also apply for Care Credit which is a veterinary credit care. Hope you can find her the help that she needs.

There are many possible reasons for the symptoms you describe but altered thirst and weight gain may indicate hormonal disease such as cushings or fluid retention. I recommend a full vet check and blood or urine screen as soon as possible

If she is constantly drinking water, losing weight, and not eating than she needs to have a workup with bloodwork and x-rays, if needed. Drinking excessively can be a sign of diabetes, kidney disease, liver disease, Cushing's, Addison's, cancer, etc. If your vet is not able to diagnose than you need to take her to a different vet who will do a work-up. It also sounds like she could have a skin infection and need an antibiotic. A vet can also aspirate the lumps to determine if they are benign. Hope you can get a diagnosis and start treatment soon. It definitely sounds like something is wrong.
