Few Pus cells found in episiotomy wound.

I delivered baby boy 2mths back. And my episiotomy stitches got dissolved earlier than expected. Then,i opted for natural healing for 2months rather than restitching Now, small wound is still open in which few pus cells found had seen in the attached report. So, doctor recommeneded Augmentin antibiotics along with the Megaheal ointment. I have some concerns or need 2nd opinion on this. And if I walk too much or sit continuosly, then it starts paining in the wound. 1. If I take antibiotics 2 times a day, Will it cause any tongue infection as alleopathy medicines are quiet hot for body. 2. Shall I intake more Vitamin c foods so as to cut pus cells? Like butter milk, garlic, mausambi juice, pineapple, etc. 3. Is there any precaution i should follow for quick heal? Does this mild infection can get bigger? M really scared.
