Clinicians at Complete Physio (Central London) address common patient questions about steroid injections and travel. We discuss practical considerations when flying soon after an injection (post-procedural flare), rare but important risks including infection and delayed allergic reactions, and how destination healthcare access and travel insurance may affect decision-making. We also cover safe considerations around driving after injections, expected onset and duration of benefit, and planning injections ahead of key events or holidays. Finally, we outline red-flag symptoms requiring urgent assessment, and discuss injection options, including standard steroid injection vs hydrodistension for frozen shoulder, plus considerations for barbotage in calcific tendinopathy.
