When methotrexate doesn’t work

Hi all, I have RA in ankles and feet. Started methotrexate in March- started on 15mg now up to 25mg and still having flare ups and suffering with plantar fasciitis too. I’ve had steroid injections and that gave relief for 2/3 weeks, self reducing prednisolone work ok’ish but had some side effects that makes me not want to take again. Can’t take anti inflammatory drugs like naproxen/ibuprofen due to another medical condition. Has anyone else not had methotrexate work for them? What other options can I ask for? X TIA X
