Since my relapse in November loud noises and bright lights bring on my symptoms - Fatigue, foot drop and brain fog. Meditation helps and anti-glare glasses. Sensory overload has a big impact on my life.
Are the symptoms from the november relapse or ongoing things? I used to get sensory overload and still do on occasion.
Although it never triggered symptoms, I would just find certain sounds unbearable and anything loud or busy hard to handle.
As it hasn't been very long from your last relapse hopefully it will get a lot better as you heal.
I'm sorry I don't have any tips or advice. I hope you recover soon.
