I do not know what you had,Did you have abscess in many organs? but the specialist was irresponsible, you should hire a lawyer and sue him, tell the physician Association that you suffered a lot, show them you prove paper and ask for the record from hospitals, no hosptial will hold back or rewrite the report, you can win the case. you suffered way too much.
infection happens, he should give you treatment, wound infection always has 4-6 treatment in the community
You are definitely unlucky to meet this doctor, I always think in US, you can look for second opinion because you are not under free universal medical care. you should have got second opinion from other hosptials, other specialists.
