So from a medical perspective the relief of inflammation can be extremely liberating and can feel godlike indeed. Getting that by suppressing your normal immune function is a very short term and unsustainable option, but there are a few other options that can have similar if less intense experiences.

Reducing inflammation by removing something you are allergic to can have a similar relieving impact, though it can take weeks to even months for the immune cascade to settle and it may remain overactive for even longer if it is a long term exposure.

Removing a long term stressor like changing job, fixing your ergonomics, changing your shoes, or moving more can have a similar impact.

Changing your diet to remove highly inflammatory foods and replace them with less inflammatory foods can also work well, though finding out what is or is not inflammatory for you can be a bit of an experimental process, some people respond to different things with an inflammatory response for reasons I don’t understand.

I found that getting rid of dairy, dropping carbs to very low, cleaning out mould, getting a much more physical job, and getting rid of chairs in general all helped me a lot with my long term inflammation issues. My nasal issues cleared, my back stopped hurting at all, my pants fit better rather than being tight on the thighs, my headaches went away, and generally life improved.
