You can ramp up DHA by taking extra. Take your regular oil so you get the EPA and then add DHA...
There is a Carlson's DHA 500mg which my son used.
But also you can buy DHA separately... it is not from fish, but is synthesized in vats. It is made by Martek in this country and there are several brands. Neuromins and Expecta are two.
Expecta targets pregnant women, but you can buy it and use it

.
I'd still take some EPA because it suppresses series 2 cytokines which are implicated in inflammation. Some nerve pain may be inflammatory in origin.
