Skin problems and bleeding

For months my pet cat, a 9 year old sweet thing with very thick fur who was declawed by the previous owners before I got her, something I've heard can affect the health of cats, has been having skin problems. I took her to a vet a few months ago, and they said she was allergic to flea bites and I should give her flea killing treatment, which I did. The flea killer I put on her seems to have made her problem worse. When I gave her a bath at the beginning of this month, she screamed and cried louder than usual. I noticed that she was bleeding on the back of her neck, in the same spot I placed the flea killer. I will be taking her to a vet tomorrow, but I am sure they will just tell me to give her more ointment.

Is there a safe, effective way to cure what seems like an infection of a cat's skin if you are aware that giving her flea ointment will cause more problems?

What was the flea product called?. Poor baby, it sounds like it's really painful  

It is called Sergeant's Gold flea squeeze. The vets all tell me I should give my pets frontline or advantage  but those are too expensive. My cat scratches that area a lot, like it's itching her real bad. I've been to pet smart and asked them about ointments but they couldn't tell me  anything. This afternoon I am taking the cat to a new vet, one she's never been to before. She has had this problem now for at least  3-4 months  and now she seems tired all the time and sleeps more than she used to. 

Unfortunately, the less-expensive over-the-counter flea applications have a bad reputation for making cats ill and even causing death.

You can get Advantage, Revolution, or Frontline online for much less than what your vet charges.  I can't tell where you are located, but if you are in the U.S., you can get Frontline at Costco.

Yes, it's more expensive, but a couple of consecutive applications, four weeks or so apart, will not only kill the fleas on your cat, but also everywhere in your house.  You can help that process along by getting a flea collar at the local store, cutting it up, and keeping a piece in the dust receptacle of your vacuum in order the kill the fleas, eggs, and larvae you pick up while vacuuming.

Thanks for replying. I took kitty to the vet. She was covered in scabs and some of her fur came completely out during the visit. She was given an injection, an antibiotic, that the vet claimed would help her skin heal and they suggested Science Diet pet food for cats with sensitive skin which I bought. I did not know that over the counter flea treatments could make cats sick but now that I know that, I won 't use them anymore. 

I do hope she gets better. She's an older cat, a sweetheart. Anyhow thanks for the advice.

We'll be pulling for your cat. I know you want her happy and healthy.
