Hi Tara,

I also suffer from low BP and it sounded like that at first so make sure you drink heaps and heaps of water as it helps bring the BP up. I also suffer from endo etc and pains in the ovary also makes me feel light headed and lowers my BP... don't know why yet im having tests done to make sure there is no cyst etc...

Another thing that can cause the dizzy spells is vertigo. Read up on it and get your DR to check you out as it is caused from an in balance in the middle ear sometimes due to a virus. I also suffered from severe heads spins ealy this year and as you did i felt nauseus the next week cause of it. I saw a neurologist and its just vertigo which can be controlled with a healthy diet and lots of iron, rest and plenty of fluids.
Good luck !
