Although epidural steroid injections (also called epidural corticosteroid injections) may be helpful to confirm a diagnosis, they should be used primarily after a specific presumptive diagnosis has been established. Also, injections should not be used in isolation, but rather in conjunction with a program stressing muscle flexibility, strengthening, and functional restoration.
Proper follow-up after injections to assess the patient's treatment response and ability to progress in the rehabilitation program is essential. A limited number of injections can be tried to reduce pain, but careful monitoring of the response is required prior to a second or third injection.
Allergic sensitivity to a topical corticosteroid is usually only picked up when an eczematous dermatitis being treated by a topical corticosteroid fails to respond to treatment or worsens. In cases of persistent or exacerbating dermatitis treated with corticosteroid preparations, corticosteroid sensitivity should be considered. However, it may also be due to irritation from or allergy to other components of the preparation such as preservatives . Lanolin , ethylenediamine , quaternium-15 and the antibacterial agent neomycin , are all known to be potent sensitisers.
