Side effects methotrexate

Skinny Keef

I’ve recently started on this for my relapsing polychondritis after waiting 6 months for my specialist to confirm the diagnosis by constant obs of my symptoms.
those that know me on here will recal my posts of migraine city in the café on a regular basis before i left somewhat abruptly due to a third party.
week one of mtx was okay I felt a lot better and had a week free of migraines for the first time in 4 years.
this week having taken 7.5 mg on Tuesday i feel terrible with a marked shortness of breath. I’ve had to take extra anti inflamms just to be able to get some air in my lungs.

Has anyone else suffered this side effect??Will it pass or do i need to get myself to the docs please??
