Does Cosentyx hurt (pain) right after the injection or infusion?
Yes, some people feel pain after Cosentyx (secukinumab), especially around the injection site. Reported issues include injection-site reactions such as pain, redness, swelling, or itching. These effects are usually mild and can improve with continued use.
Can Cosentyx cause body pain or make aches worse?
Cosentyx is generally used to treat inflammatory conditions (like plaque psoriasis, psoriatic arthritis, and ankylosing spondylitis), so many patients feel less joint or body pain as the inflammation settles. However, like other biologics, it can still cause side effects in some people, including muscle aches or other discomfort.
What side effects are more concerning than “hurting”?
Seek medical care urgently if you have symptoms that can suggest a serious reaction or infection, such as:
- Trouble breathing, facial/lip swelling, or widespread hives (possible allergic reaction)
- Fever, severe chills, or signs of a significant infection
- Severe worsening pain, persistent or spreading redness, or pus at an injection site
Could pain be from something else while you’re on Cosentyx?
Yes. Pain can come from the underlying condition if it is not fully controlled, from other medications, or from infections that happen independently. If pain persists or worsens after starting Cosentyx, clinicians often check disease control and look for infection or other causes.
When should you call your clinician about pain from Cosentyx?
Contact your prescriber if:
- Injection-site pain is severe, lasts more than a few days, or keeps recurring in the same way
- You get new or worsening pain after starting or increasing the dose
- You develop signs of infection or a possible allergic reaction
What can help with injection discomfort?
If your pain is injection-related, clinicians commonly recommend strategies like rotating injection sites, using proper injection technique, allowing the medication to reach room temperature before injecting, and using cold packs if your clinician agrees.

If you tell me what kind of pain you mean (injection-site soreness vs joint pain vs stomach pain) and when it happens after each dose, I can help narrow what’s most likely and what to watch for.
