My mom has chronic ailments

My mom (name edited out for privacy), had a kidney transplant because both of hers failed previously due to polysistic kidney disease. But the medication she takes to not reject her transplant makes her very ill.

And she has been having horrible headaches when she wakes up and full body pain all day long every day but is not allowed to take anything for her pain so she just suffers.

She also has high blood pressure and the medications for that make her sick also. She is always feeling weak and upset and is in unbearable all over body pain. She may also have fibromyalgia but has not been diagnosed of it yet.
