Have you tried googling your condition to find support groups for this? They might have ideas for good physicians to see that will help you with this problem. It's just an idea. I have a somewhat rare condition called a dysautonomia, and through an online support group I was able to find a list of doctors that treat this which was great.
Over the past 4 years I have tried numerous doctors; my family physician of course, 3 gastroentrologists, 1 urologist, 1 liver specialist, 5 naturopaths, 2 osteopaths, 3 chiropractors, 7 massage therapists, plus others, etc. I spend over $5000/year to try to find out my problems. Most of the specialists told me it was my liver or that it was all in my head and I should see a psychiatrist - so I was trying to combat that angle; now I find out that it is intercostal neuralgia along with bacterial infection that nobody knows about. I am happy to find this out but I haven't found anyone who can help me yet. I believe one of the osteopaths and my acupuncturist will be able to help. Thank you for your support and for this web site, it helps
Welcome to the gastroenterology community! While I don't know anything about intercostal neuralgia, after researching it on the internet, it seems as if you are not following the recommended treatment for this. I would recommend finding a doctor that knows about this and is willing to help you with this and help you work through a treatment. I would not recommend self treating this condition as you could cause yourself problems. Good luck.
