If the medicine for IIH makes you feel pins and needles, you need to inform the doctor who started you on that treatment. The dose will need changing/ reducing or stopping.  The only natural remedy for IIH is losing weight (pardon, but you have not mentioned if you have body weight challenges but IIH usually but not always affects women who have a high body weight). Otherwise, if the IIH is causing severe headaches or loss of vision, surgical treatment offered by a Neurosurgeon is the only option to protect vision.
