You have asked this question at least twice before. There is no definitive answer. The proper question would be, How much force can the brain tolerate ? Research suggests that the brain can tolerate 20 to 40 G's without any problem. I doubt your twitches even reach a level of 10 G's.

I think your greater risk is the impact your anxiety has on your healing. Anxiety causes the brain's chemistry to get out of balance. This can slow recovery.
