The hearing seems to be slightly better, but no significant change. Since the ringing in the ear is improving, you can wait a little longer.
Vitamin D supplements can be taken. There is a drug called ginkobiloba which has shown good effect in a proportion of patients, but it has to be taken for months together for any noticeable improvement. The hearing loss pattern is that of nerve weakness, usually this does not improve. Also supplement with optineuron tablets.
