I'm pregnant and have been suffering from neuralgia for a long time; the worst was intercostal neuralgia—first in my back, then in my chest under the two lower ribs.
An osteopath saved me (two sessions, a week and a half apart, to relieve tension), along with warming in every possible way: a warm jumper, compresses, ointments, heated stones, my husband massaging the area...
It took a long time to subside, nearly a month, painkillers didn't help at all, but at some point, I accepted it, and then positive progress began🤷🏽♀️
