Intramuscular Injection: Provides an extended duration of therapeutic effect and fewer side effects of the kind associated with oral corticosteroid therapy, particularly gastro-intestinal reactions such as peptic ulceration. Studies indicate that, following a single intramuscular dose of 80 mg triamcinolone acetonide, adrenal suppression occurs within 24 - 48 hours and then gradually returns to normal, usually in approximately three weeks. This finding correlates closely with the extended duration of therapeutic action of triamcinolone acetonide.
Kenalog can also be injected directly into acne or pimples at the sign of a breakout to reduce the infection, redness, and swelling almost immediately. While this quick fix is perfect at the onset of a pre-event breakout, it’s only reducing the symptom and not treating acne at the source – or preventing future breakouts from occurring. Like the treatment of a keloid, it’s especially important when treating acne to follow a holistic approach. Kenalog injections are often used in conjunction with laser acne , light therapy , chemical peels , and a medical grade skincare regimen in order to achieve the best results.
Sounds like they had a DeQuervain’s injection (if it’s intratendinous instead of just under the tendon sheath there can be a lot of resistance…especially if using a tuberculin syringe/needle), and then had either a trigger thumb injection or an intraarticular injection of the 1st carpometacarpal joint. Either way, they shouldn’t have had “nerve damage” from either injection. The “nerve damage” was probably already there. Without a pre- and post-injection EMG/NCS, it’s impossible to know for sure. The skin atrophy and other signs can be relatively common with kenalog and other insoluble steroids. I don’t what the “thumb locking” is unless the patient means trigger thumb. Some physicians will use sterile saline injections in the atrophied area to speed up the recovery.
