Blood pressure & sezuire medication for neuro issues???

I went back to another specialist (god knows what # he is) regarding my situation (in a nutshell: pins and needles/tingling sensation across entire scalp, episodes of slurred speech, memory loss, motor skill impairment) and his result was:

-Low blood pressure medication (Fludrocortisone) which I found EXTREMELY odd because lets face it, I've been to the dr/hospital MANY times and I've never once been told that I have low blood pressure (being a 22 year old female) also, the side effects are outrageous:
    * Sodium and water retention
    * Swelling due to fluid retention (edema)
    * High blood pressure (hypertension)
    * Headache
    * Low blood potassium level (hypokalemia)
    * Muscle weakness
    * Fatigue
    * Increased susceptibility to infection
    * Impaired wound healing
    * Increased sweating
    * Increased hair growth (hirsutism)
    * Thinning of skin and stretch marks
    * Disturbances of the gut such as indigestion (dyspepsia), distention of the abdomen and ulceration (peptic ulcer)
    * Decreased bone density and increased risk of fractures of the bones
    * Difficulty in sleeping (insomnia)
    * Depression
    * Weight gain
    * Raised blood sugar level
    * Changes to the menstrual cycle
    * Partial loss of vision due to opacity in the lens of the eye (cataracts)
    * Raised pressure in the eye (glaucoma)
    * Increased pressure in the skull (intracranial pressure)

-He also told me to try Lyrica which is prescribed for people with seizures.. but only after seeing if the blood pressure medication works.

I am leery and not hopeful in the least. Any suggestions/comments? Anyone on these medications or taken one or the other at any time?

Keep in mind I am also on Zoloft (which I take daily 100 mg) and that dr was def made aware.
