I recently developed vertigo.I lean to right side, weight gain, short term memory loss, buzzing in ears, hair loss. If I walk in the dark, I get dizzy, I have lost my equalibrium. went to ent; no fluid in ears, crystals in the ears maybe cause, I did exercises, but no help.I type at my job and recenly have spelled words wrong. I am an excellent speller.Loss of depth perception also.
