48,M.In Mar.in HI,became ill.Sore throat/congestion,bright light sensitivity,tongue burning,head/ear pressure,light headed & difficulty focusing(such as after an alcohol drink),perhaps due to head pressure,weak.Week later,develop burning pain in balls of feet when standing,& pain in fingertips when pressure applied,& calf muscle fasciculations.Other symptoms got worse.Saw 2 neurologists in late April,& each did an EMG/NCV-normal.Normal sinus CT.A brain MRI w&w/o infusion was done mid-May & was normal except patchy high-sgnal on T2-weighted images within right mastoid air cells suggest fluid &/or mucosal thickening.The latter was dismissed by neuro.Diagnosis by both-small fiber peripheral neuropathy(PN)/benign fasciculations.Numerous blood & urine tests were normal(CBC,metabolic,B12,Sed,TSH,ANCA,heavy metals)Saw ENT in June,& no fluid,but put in ear tubes-did not help.Since mid-June,PN & tongue pain & head pressure much worse 24/7.Developed in mid-June feeling of being hot 24/7 when ambient temp not,& am not hot to the touch or flushed.Sweating OK.ENT thought eustachian tube dysfunction for ear pressure,7/1/05 gave prednisone(60mg 2 days,tapering 10mg each 2 days)& Ceftin.Ended prednisone and Ceftin 7/12.Then head pain worsened(worse pressure pain but also random sharp pains)& worse hot feeling-head,legs,arms,even trunk feel like on fire,but cool to touch.A repeat of MRI 7/14 was normal.Can't go out-too hot feeling,even hot in AC.What caused all this?Why have PN,tongue pain,head pressure worsened since mid-June and more this week? Why did severe hot sensation start in June?
