Diagnosed with AS in late 90's, started on ENBREL 2009, after hip replacement, stiffness was minimal, and pain literally vanished but now in 2022, the ENBREL is NOT WORKING as Well as before; back pain chronic and neck and shoulders horribly stiff and sore ALL THE TIME.
I guess my question is it my aging causing less effectiveness of the ENBREL or is It the ENBREL??? ANY FEEDBACK WILL BE GREATLY APPRECIATED, THANK YOU!!
