It's probably been close to two months now and still I have no answer. It first started with lightheadedness and dizziness that brought me to my knees. Shortly after, these episodes were accompanied with a headache that refuses to go away, numbness down my left arm and leg, and moments of fogginess or confusion. I have had CT Scans of my brain, blood work for lupus, mri's of my brain and neck, and a lumbar puncture. I have also seen a neurosurgeon, neurologist, pcp, and endocrinologist just in case it was my thyroid acting up. Everything has come back normal, except the blood work, according to my neurosurgeon, showed some inflammation but he was unsure of what it actually meant. I read the report and it states that my c3 & c4 was high, along with the drvvt screen secs. and ratio were a bit high. But since he only tested what a rheumatologist told him to test for he doesn't know what this means but doesn't feel it means lupus even though the report recommends i be retested in 12 weeks. After another episode of numbness and fog onset yesterday I spoke with a nurse of my insurance company who suggested that this could be a cardiac issue or a bad reaction to a depo shot i had around the same time this all started. Of course none of the doctors are calling me back at this point and I am starting to feel hopeless. I know I feel bad, I know something isn't right, but I seem to be the only one who cares and Im starting to get really scared. Any thoughts would be greatly appreciated. (The headache is constant and i have been put on a variety of meds that has not gotten rid of it. The numbness comes and goes and sometimes stays for a period of time, a few hours or so)
