perineal tear help!

So I had a second degree tear during my daughters birth on October 6th. So I'm about 3.5weejs post partum. The soreness from my tear was minimal right away I had no issues going to the bathroom and no pain or stinging at all. I used the peri bottle, tucks pads, anti-septic spray etc, religiously and still do but within the past week or so it has started to burn/sting when I urinate. And not in the urethra like I would feel a uti. It's a burning a bit further back where the tear I would think would be. I checked with a mirror and cannot see anything and I don't see hemorrhoids either. I will be calling the doctor today but it's next to impossible to ever get in to be seen last minute. but wondering if my tear could be infected now or if this is normal healing?? Or if anyone has any other advice or things that could help ease the pain and discomfort?
