Your response is similar to mine: idiopathic intracranial hypertension. So far, neither condition has shown up much in these Mayo Clinic support groups, yet IIH has been linked to both Covid and a lawsuit filed against Bayer Corp for IIH caused by the Mirena IUD. https://www.forbes.com/advisor/legal/product-liability/mirena-iud-lawsuit/
For me, IIH led to a spontaneous cerebrospinal fluid leak which was plugged and implantation of a VP shunt.
