For a mother who does not read, a sister with no phone of her own, or a woman a health worker saw this morning. You describe the situation — you do not sign her up for anything.
Step 1 of 4: Say who it is for, and what to ask
This is her question, not yours
This question is about the woman you are asking for, not about you. Anything a doctor writes back is educational information about her situation — it is not advice about your health, and it is not a diagnosis of hers.
You will get a private link so you can check it, add to it, and read the answer when it
arrives. What you will not get is the power to put her question on a public page.
That decision is hers and there is no form on this site that lets anyone make it
for her.
