Immediately after getting CK, I felt like I'd been hit by a train... no waiting 2 to 6 months for me! I was profoundly fatigued, short of breath, balance was about 15% worse (subjectively) and my skull felt numb for two days. It took me two months to lose the debilitating fatigue and six months to have my balance and vigor come roaring back. At about 3-1/2 to 4 months post-CK (can't remember exactly when), I had an episode of hyperacusis, with attendant hearing loss, that lasted about a week. Strange enough, my tinnitus got reduced by about 90% right after treatment and has since stayed subdued.
So, yeah, all bets are off. Everyone responds differently.
The good news is that I feel much better now. My balance is about 80% improved. Energy level feels great (virtually normal). I did lose some hearing on my AN side (around 15 dB or so), but still have useful hearing on that side.
It does get better. You just have to wait it out. And stay as healthy as you possibly can. It makes a huge difference if you're exercising, eating well (avoid sugar and very oily foods) and, especially, if you're getting enough sleep and staying hydrated. You want ample flow of good clean blood feeding those traumatized cranial nerves and keeping them happy. Walk, drink water, eat vitamin-rich vegies and omega-3-rich fish, keep your blood sugar stable. It all makes a BIG difference. You'll be feeling better soon.
Best wishes,
