Bit of a long post.
So, I am a 28 year old male, 190 pounds. I have been extremely healthy most of my life up until late December of last year when I caught some viral illness that made me lightheaded and nauseous for nearly three months, and lost 30 pounds despite little exercise. During this time I took ondansetron (zofran) and meclizine (antivert) on and off. During this period my anxiety spiked massively so I went to see a psychiatrist and he prescribed me Venlafaxine (Effexor). I think I would’ve reacted badly to Effexor regardless, but on top of that, my psychiatrist didn’t tell me not to mix it with zofran. I only took it for two days because I had a bad reaction, and that slowly diminished after a week. Went to see a doctor because lightheadedness persisted and he diagnosed me with acute sinusitis and prescribed me doxycycline. The antibiotics helped with sinus issues, but caused horrible headaches and depression. About a week after finishing the five day course of antibiotics I finally start to feel a bit better. Then my doctor prescribes flonase. The first day I take just one dose and within an hour I start to feel pins and needles in my arms and then have a migraine with aura. I have no history of migraines prior to this. I assumed by the next day (March 19) my body would adjust to the medication and side effects would diminish. I was wrong. I experienced hyperactivity, depersonalization, dizziness, blurred vision, headaches and insomnia. I woke up the next morning fatigued with terrible headaches and back pain. After the back pain subsided I felt uncoordinated and had pins and needles sensations in my arms and legs. Since then (early April) I have experienced a sensation of internal tremor (rhythmic pulsating) that comes and goes throughout the day, frequent migraines with aura, occasional balance and coordination issues, brain fog that comes and goes, and numbness of the limbs and face that comes and goes.
Since March 19 I have had three seizure-like episodes that only lasted a few seconds. In early April I had one where I felt an internal tremor and depersonalization, but no loss of consciousness. Then about a week ago I felt a jerking sensation in my leg and an impending sense of doom. Two days later, similar, but this time the jerking was in my back.
I have not taken any medications since March 19, and my doctor ran blood tests: Complete Blood Count and Automated Differential, Comprehensive Metabolic Panel, TSH, and B12 and they all came back normal.
But I am really starting to worry if I might have brain damage, or something. Are fears founded? Or will this likely go away with time? Thank you.
