Hello I am BAYS, I totally know what you are dealing with I myself dealt with severe enemia my level was 5.6 . Phew was scary time for me.
1. iron infusion: I have had many they take about 30 minutes to an hour and I didn't feel any pain while having it. Maybe site a little sore. Just like another IV given. It looks brown in color thick like molasses. I tasted a hint of Licorice while IV was being given. One more thing best place to have IV when giving iron infusion is the fold of your arm or in that area. Other areas can make that area more painful and area hard. But if that happens warm packs and massage area. It gets better.
Extra note my enemia was so bad I also was given Epigene shots. To boost my blood levels it was a life saver. I needed both before my surgery to get ready and after. I stop all in January of 2021 no more iron or epigene treatment. I still take iron twice a day now.
I know we all different but I would use to make protein shakes with Spinach and strawberry banana peanut butter powder and whey protein and beats. And of course with my iron supplement I also used Probiotics. And eat liver if u can best boost. But I don't like it.
2. Enemia headaches 😫. I used Tylenol don't use ibuprofen it does make bleeding worse. I just tried my best to stay hydrated I put fresh mint and lemon and a tiny slice of ginger in my ph 9.5 water. And also sucked peppermint. But also rest and don't over due it your body working really hard.
I have also used edibles for my headache 🙃 to relax me because the headaches can be a bit much.
Wishing you the best with this and take care. I am 👂🙂
