Diet for inflammation?

Do you mean she has arthritis? There are medications for this. My MIL slept in a recliner because the bed was too uncomfortable.

You are probably better off googling this question, but stick to the reputable sites like harvard health and the arthritis foundation.

Inflammation of what? How does this manifest? Who diagnosed it? I think if you mean inflammation in the hip, this can come from any number of problems but most often is from deterioration in the joint. This cannot be fixed by diet. Have you spoken to doctor about what can help. Does she require steroids at this point? Really need a lot more information here. Wishing you luck.
