Tootsie in bad shape - near death + head abscess

[Tootsie]

My little 2yo hamster Tootsie is having a variety of issues.
Last week she was suddenly cold, couldn't stand up, looked like she was dying. I put her on a heating pad, she lay on her side breathing really heavily and foam came out of her nose. I thought she had died BUT then suddenly she was up and moving and has now been her usual self for a week.

Then she developed a huge lump on her head. It was hard/squishy - we researched and deducted it was an abscess. There are no vets near that take hamsters so my husband and I had to operate. We cut it open and squeezed out disgusting, smelly pus. Her head was like a deflated ballon. Now she has a huge black spot on her head and the hair is falling out. The abscess has moved to cheek now. She is her usual self during all of this but we do not know what to do. Operate on the other abscess or just leave her alone. It's breaking my heart to see her in this condition.
Any advice would be welcome.

You really need to see a vet as she may well be in pain. Surely there must be someone that can see see her. The black spot sounds like the tissue has died. Cutting in to it open the abscess may have allowed bacteria in to her bloodstream and could have been very painful. She needs pain relief before any operating as well as antibiotics and you are not experienced to know what vital structures may be underlying. Phone around and say it's urgent. Post your location and try a vet finder near me site and try and get her seen or at least someone who may be able to give her rest.
