My son "limbolander" gets this throughout the day all over and it is random. Some days and sometimes are worse than others. His Neuro says they are pseudoexacerbations because they are not causing damage, they are not new and they are caused from damage already done. This is really frusterating to him on some days! He gets the Zaps and they really hurt. The tingling and numbess comes/goes and sometimes sticks around a while. He takes Neurotin and says it kinda helps but it's better than without it. So sorry this is happening. As a parent, I make him rest and drink plenty of fluids. When he over does it gets really bad. We are on day 9 of an exacerbation (I think) and mainly all down the left side from head to toes. Just waiting and watching. I wish you the very best!
Is yours worse or stronger at night? Mine tends to be at its strongest when my body is winding down/tired or when I get fatigued.
I get that when I "overdo it", with heat, and with both true and pseudoexacerbations. I also have had a sensation of mild vibration all down my left side since last June. Is this similar to what you are experiencing?
