I wrote to you at an earlier time. Since then I have had bloodwork done to rule out, Lupus, RA, Lyme, Multiple Myeloma, Thyroid disease, HIV, my sed rate is normal, lipid profile, normal, SPEP/IPEP, normal, brain, lumbar, and c-spine, normal. My gynecologist just sent me last week for blood work to measure my hormone levels, I had this done on the third day of my cycle, don't know results yet. My symptoms are: Migraines (which I never had a headache before this all started 5 years ago), heart palpitations, awakened at night with what feels to be an internal trembling inside, periods change monthly, anywhere between 22-30 days apart, sometimes heavy lasting just a day, sometimes lighter, lasting just 3 days. I never have a period longer than 2-3 days. My hair seems to be dry, and I have weird feelings on my skin, like bugs crawling, sometimes it feels hot and burning. The worst is the bug crawling feeling on my scalp. My neuro put me on Metanx. She told me that she was going to make these weird feelings go away. She told me that it will take a few weeks and you will notice a difference. Well I was 1 day into my monthly cycle when I started these pills Dec 22, by Dec 30, there was a big difference, the feelings had gotten better by 80%, and I had lots of energy. Well the 4-5 days before my period started this month it all came back with a vengance, now that my period is over it is gradually getting better. Do you think that this is all hormonal? It seems so strange that I was feeling so much better, then BAM, my period started and everything went haywire. Thank U!
