No, MRI is only recommended if red flags are present or pain persists beyond 6\u201312 weeks. 2. Can X-rays detect herniated discs? No, X-rays show bones but cannot visualize discs or nerves; MRI is preferred for soft tissues. 3. Is it safe to get repeated X-rays or CT scans? Repeated imaging increases radiation exposure, so tests are only done when necessary. 4. How long should I try conservative care before imaging? Typically, 6 weeks of conservative treatment is recommended if no red flags exist. 5. Can imaging findings guide treatment? Yes, MRI and CT can help doctors plan surgery or targeted therapy, but mild findings without symptoms may not require treatment.<\/p>\n","protected":false},"author":2,"featured_media":7100,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"footnotes":""},"categories":[2,6,9],"tags":[1977,176,18,186,8,104,871,21,12,33,174,193,1112],"class_list":["post-7099","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-articles","category-diseases-conditions","category-health-issues","tag-back-pain","tag-causes","tag-disease","tag-happylife","tag-health","tag-healthylife","tag-mri","tag-o-health","tag-ohealth","tag-ohealthtv","tag-treatment","tag-wellness","tag-x-ray"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts\/7099","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/comments?post=7099"}],"version-history":[{"count":1,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts\/7099\/revisions"}],"predecessor-version":[{"id":7101,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/posts\/7099\/revisions\/7101"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/media\/7100"}],"wp:attachment":[{"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/media?parent=7099"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/categories?post=7099"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ohealth.digital\/index.php\/wp-json\/wp\/v2\/tags?post=7099"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
