hello and welcome to hcm forum,
As you wrote , pain after a month of getting your wisdom molar extracted is something which needs to be checked thoroughly.
without checking clinically, i cannot suggest you any treatment but i would like to ask you to do warm saline rinses or betadine
rinses, in order to relief some pain.
might prescribe you antibiotics and anti-inflammatory only after ruling out the cause.
so kindly visit your dentist soon.
i wish you good health.
