Tips for avoiding achilles pain?

Hi everyone, so I’m 25F and have been doing incline walking on a treadmill (12-3.1-30) on weekdays for the last 6 months or so. I have also increased the amount that I walk on weekends, sometimes my bf and I will walk 15k steps per day.

I have super muscular calves from growing up a ballerina— so I don’t think a lack of calf strength caused this, but the last few days my right achilles has been hurting pretty badly. I have started incorporating some light weight training a couple of days per week into my fitness routine so it could be that— but I have a feeling the 14k step walk I did on Saturday (which included a pretty big uphill jaunt toward the end, and I ran some of it) is what did me in.

Since then I have what I believe to be an inflamed achilles or some tendinitis in my right ankle. The past few days I’ve taken a rest from the incline walking— but I’m wondering if anyone has experienced something similar and how you healed it?

I mostly have pain (3 or 4/10) when I do something like walking too quickly or on an incline, or calf raises/standing on my tippy toes and for a while after. However, when I rest for a few minutes and start walking again after, it feels better until I reach that walking threshold again. Any advice? Is it bad to push through the pain? It’s killing me not being able to get my steps in.
