Do women with fibromyalgia lose their symptoms temporarily while they are pregnant?

Often worse. There are few studies on fibromyalgia in pregnant women. A temple university found that women with fibromyalgia had more symptoms of pain during pregnancy than women who did not have fibromyalgia. Also, fibromyalgia symptoms seemed to be exacerbated during pregnancy. Pregnant women with fibromyalgia may experience significant pain, fatigue, and psychological stress, especially in first 3 months.
Yes and no. It depends, because pregnancy can interfere with sleep and this can exacerbate fibromyalgia. Stress during pregnancy can also aggravate fibromyalgia. Finally if pregnancy decreases your exercise, this can also aggravate fibromyalgia.
Mostly not. Pregnancy worsens #fibromyalgia symptoms. Increased pelvic girdle laxity, fetal weight, increased mother body mass and larger breasts all impact chronic muscle spasm attendant with this disorder. Complementary and alternative therapies can help. See two comments sections below.
