In that recording the drums are a little to the right and so is the sax and the drums are pretty bright too. But looking at the picture I see you may have panned things that way according to the way they were set up live which is fine.
 
Personally I would not have mixed it that way.  I would have the bass and sax centre and the guitar little to the left and the drums a little to the right.  Remember this recording might still be played in a situation where the right channel might may not be working and then the group would be seriously out of balance.
 
If you do have issues with one ear compared to the other and it is permanent then it is better to adjust your monitors accordingly. e.g. make one a little louder and brighter (many active monitors offer a brightness setting so use it!) than the other because if you are not careful you will end up pushing the weaker side of your hearing in order to make things sound normal to you but it won't sound that way elsewhere. 

You could try using ear buds/headphones and swap L/R to see if everything holds up. 

I was using channel tools and flipping it by enabling and disabling the plugin.
 
Thanks for the idea, Jason White. I'm all over it.
 
@Jeff, I really don't mix for someone to listen in mono (blush). I mix for stereo listening where both speakers work. It's 95% of the people who listen to what I mix.
 
It's true that I matched the stereo spread the band had live. It's also true that the mic in the drums was above the cymbals so there is a ton of sizzle. It's one of the first emails I got from the guitarist, saying he loved it. I could dull it down, but ...
 
I like the idea of adjusting the monitors to compensate. I hadn't considered that. I'm really grateful for the suggestion.

My partner in the Sock Monkey band just ( finally) got hearing aides. He was the bass player in a 8-10 piece R&B band which had a horn section. Those buggers can drown out a Fender Twin. 
Curt had a fairly powerful Bass rig with a 2x10 cab right at his shoulders and not far away. Anyhow,, it was brain numingly loud up there. So now we pay nice laid back acoustic stuff and he's always' needing more monitor. I use in Ears so I'm fine but he was reluctant and now with his Aides he seems happy. His have a few settings he can change with the buttons or bluetooth remote and he had one of the programs optimized for live playing. Seems to work and he no longer shouts when he talks.
 
I've always been careful of my ears but I know my hearing is fading. I can't hear speech now if there's a lot of background noise. Hearing tests are free at most of the places they sell the aides. 
 
It's cool what they do. My wife followed through with hearing aides so I got to watch them being programmed. 
They test your hearing and you get a little EQ graph just like we use for our gear.
He plunks that in the software and starts messing with the EQ of the device until you get a flat line. 
In other words, if there's a dip in your hearing in the right ear at 800HZ of 10db they give you a 10db boost. Just like playing with a real time analyser. 

Geoff, it's my understanding that hearing loss from short-term exposure to sounds < 140 dB is usually temporary. That's the good news. The bad news is that recovery normally takes 1-4 days. 4 months is too long. You should make an appointment with your GP, who will likely refer you to a specialist.

...The hearing tech said musicians are the hardest to accommodate....
 

I'm worse! Musician and an Electronics Design Engineer who designed an Integrated Circuit for a hearing aid. (Granted it was an Analog version). When I asked them questions concerning various parameters, their eyes just rolled. I assume they know how to make hearing measurements and tweak the some parameters to try and make it work.
 
Glad yours is working out.

I've been wearing a set of behind the ear Siemens hearing aids for a couple of months.  I have a dip in the mids that has been graphed by an ear specialist.  They can basically program them to boost the frequencies that you are missing.  I find that it improves my ability to recognize speech and television pretty well.  It's Ok, but not great with music.  
 
I hate wearing them when playing guitar.  With guitar, it changes my tone dramatically and is not a pleasant tone.  Much harsher for some reason.  The first time I noticed it, I kept turning all the dials on the amp and could not figure out why is suddenly sounded like butt.  I am thinking that I have bad tubes or my transformer is going out.  I finally remembered that I had the hearing aids in my ears.  Took them out and was like....wow...there is my tone again.

Let me guess. You're dip is between 2KHz to 4KHz. If so, that's typical since average hearing peaks at 4KHz and if you've suffered hearing damage form playing in a band with the speakers maxed out, 2KHz to 4KHz is the first to go. BTW a baby's cry is centered around 3.5KHz, Mother Natures way of protecting the baby.

Typical hearing aids are designed mainly for voice. Did they disable the compressor/limiters in your hearing aid to put it into a "music mode" option?

I've been playing with the output balance on my interface.
 
It's been interesting. Again, when I pop my ears, sometimes it sounds very clear. While listening to a frequency sweep, there was some stereo field shift (one ear duller at a frequency than the other) but in general I can hear up to about 14 kHz.
 
For some reason my right ear just gets duller across most frequencies when I listen to music at what I think of as normal volumes for sustained periods of time. It actually sharpens in silence, but when I turn it up and leave it up it dulls. Like it's letting the ear drum loose as a protective measure.
 
I'm no longer listening to phone meetings in my right ear.
 
Thanks to everyone for your posts!!
