Ingrown hairs and shaving bumps haven’t gone away in 2 months!?! What to do

Okay TMI but I shaved back in the ending of January and really fucked up. I used a really old razor that I shouldn’t have used, didn’t exfoliate or use any shaving cream. I didn’t shave in the right direction and literally rushed and cut myself. I was going swimming and did this in 10 minutes and now I deeply regret it. I’ve been trying to let it heal and let the hair grow out but the shaving bumps and ingrown hairs haven’t gone away. They still are there and some are painful. I don’t know if this calls for medical attention but I’ve never had so grown hairs and shaving bumps for this long. What do I do??
