Hi. I have had ACNES in my sternum & left chest for over 2 years. This is what I have learned so far with treatment that works for me: gabapentin medication, multiple cold laser therapy which lessens the pain events I have each week which I found at Mounds View Chiropractic clinic, Garden of Life CBD 800mg lotion. I have found there are no real specialists for ACNES. You will most likely get referred to a pain clinic. I went to a pain clinic & I felt their treatment was pretty radical with nerve blocks (had them didn’t work well), pain pumps (don’t want to be on narcotics) etc. this was the best balance I found that allows me to live a pretty normal life. I still have pain days but they aren’t as intense or last as long as they previously did.
