As to your anxiety take royal jelly capules after breakfast this should take care of that and for your dizziness have chickweed tea or capsules
Well, if the bumps are no larger than your thumb, these are likely cysts, which will form on many places on the body, they happen from clogged skin pores. Seeing a regular doc is necessary, he may refer you to a dermatologist if he thinks they're cysts, or he may refer you to a neurologist if he thinks they are interfering with your nerves. You say your iron level is fine now, but I can tell you that many women have wildly fluctuating iron levels due to female hormonal changes. Again, seeing the regular doc, he can do a general checkup to make sure your loss of balance and dizziness are not related to something like a circulatory problem, and some bloodwork run to see just what your iron and vitamin levels are looking like. Dizziness is most definitely one of the "side effects" of too little iron, but can also signal a variety of other health issues, thus the need to see a general doc.
As for your anxiety, staying active, drinking plenty of water, and eating well-balanced meals are key to keeping anxiety in check, as well as taking a multivitamin and mineral supplement twice a week. But anxiety can also be caused, again, by a variety of health issues, which a general doc can check for anything out of the ordinary that may be contributing to this, like endocrine levels of all your hormonal glands. If he finds any of those readings off, he'll send you to an endocrinologist, for example. You need a general checkup to look into all these things, just tell that doc exactly what you've told us, and he'll know what stuff to look for.
