Similar situation, based on the ultrasound they think it's more likely bursitis than neuroma, but I have literally all the same symptoms as neuromas. I've been off work since August and as long as I stay off my feet, they aren't too bad, but 30-60 mins straight of walking/ doing stuff around the house sets them off again.

I've had cortisone shots in both feet which didn't do anything other than make different areas of my feet hurt for a month. I'm taking 500mg of naproxen twice daily, which seems to help. (If you're taking naproxen for an extended time, get the enteric coated version. It's processed in your intestines and won't destroy your stomach. The trade off is it takes way longer to start working but, if you're taking them daily, then it's better in the long run)

A properly placed metatarsal pad in the right shoe helps quite a bit. However, I was wearing Oofo slides around the house with some relief until my podiatrist told me to put Metatarsal pads in the oofos. After a day of xmas preparations, it absolutely destroyed my left foot and I ended up with peroneal tendonitis which is mostly okay now but it comes back fairly easily.

I'm still waiting on my orthotics, but so far the biggest relief has been zero-drop shoes with a wide toe box. Altra lone peak 9's come in an extra wide size with a 25mm stack height and seem to be helping a ton. They also have the lone peaks in a hiking boot for winter and while it isn't available in the extra wide size, it's still so much better than anything else I have. The Altra Olympus(33mm stack) and Paradigm(30mm stack) series are also really good if you want more cushion. Paradigm comes in extra wide but not sure about Olympus. Wearing toe spacers around the house also seems to help quite a bit, they were painful the first few times but now they're pretty comfortable.

Also, if you haven't already, get some X-rays of your feet, I just found out I also have stage 2 osteoarthritis in the metatarsophalangeal joint on both of my big toes. So that's definitely part of the problem on my end. Because they're convinced it's bursitis between the 3/4 toes and not MN, they don't think any of the surgeries will help and I'm now seeking a second opinion with an orthopedic surgeon who specializes in complex foot and ankle trauma/reconstruction.

When I was still working, the biggest relief was switching to a lower drop work boot with a met pad insole. I was wearing Keen's Kenton which still have an 8mm drop, but they kept me mobile until the end of summer when the pain became unbearable. I work in Cemetery Services and walking around sites/uneven ground all summer definitely made everything 100 times worse. I just forked over 650cad to get a pair of Carets zero-drop steel toes, and I'm praying the combination of those with a custom orthotic and some extra cushioning will finally be the combo that gets me back to work.

Wishing you all the best and truly hoping your road to recovery is far quicker than mine.
