Bruised Tail Bone

So a few months ago I started feeling pain in my tail bone area after squats and deadlifts, I analyzed my form and didn’t really see anything wrong, and even asked the opinion of others. After awhile I noticed that there was a black mark on my right side of my tail bone and cocyx. I am almost certain it is bruised but have no idea how it happened.

Anyways I did some research and found the best thing I can do is let it rest, but it has been over 3 months and little has changed. I haven’t been squatting or deadlifting since or really any lower body movement (I have tried to do adaptations of squats and deadlifts ie front squats, zercher squats, sumo deadlift, Romanian deadlift, 1 legged deadlifts, lungest, etc).

So I am just wondering is there any thing I should do to help my recovery, and is there any lower body movement I can do at the moment to at least allow me to retain the strength I have now and muscle mass. Thank you!

I hurt mine in early feb and its only now starting to get better. They have to deep acupuncture to help it
