I'm not a doctor, all I can share is my experiences. Don't know what kind of discomfort you have, but I know that we started running at a similar time.
Yeah, I had plenty of niggles and stiffness at first. Heel, Achilles, calf, knee, ankle. Figured out the side knee pain had to do with my IT band that was just working too hard too soon.
I was so proud to see the gains I was making that I just wanted to go faster. What an idiot I was.
So I took a week off. What enabled me to run largely pain free for the past couple of months is the following:
I just started running slower. Easier, focusing more on form and efficiency. Foot strike, heel lift, butt in, shoulders relaxed, arm swing, head straight. YT videos helped a lot in this regard.
And stretching! (Must admit, I am lazy with strength exercises, can definitely improve there).
And not approach every training run like it's a race.
Yes, my average pace has dropped considerably, and sometimes I feel like I stay too much in my comfort zone, but I'm running pain free for longer distances.
