Damage through improper practice

Hello Dhananjay,

thank you for providing this service.

Two and a half months ago, I (36) practiced Uddiyana bandha for the first time and maybe a bit excessively - and most probably not correctly.
Ever since, I feel dizzy most of the day and it seems as if I cannot move my eyes as quickly as before.
Rigorous physical activity makes the vertigo more intense and it will stay that way for 2-4 days afterwards; if I stay physically inactive as much as I can (except for the normal day-to-day activities), it will gradually decrease in intensity without going away completely.
Walking around in a dimly lit room also makes it worse.
I also feel a pain in the chest area coupled with a difficulty in breathing after doing something physically a little more demanding, which is something I have never experienced before.

Overall it feels as if a valve in my body has been compromised so that too much pressure is let into my head.

Although I do not trust academic medicine, I had to report this to a doctor for work-related reasons. So far my eyes and the inner ear have been tested, and everything checked out ok. Next on the list of tests is an MRI, but I refuse to undergo such a procedure after having read about the horrible side effects some people got from that. As far as I understand, it is just to exclude the possibility of a tumor, which I know is not the cause - explaining that to the doctors will be another story though.

For the time being, I have completely stopped practicing Pranayama.

My questions:
1) Do you happen to know if the damage is permanent?
2) If not, is there anything I can do to speed up the healing process aside from practicing Brahmacharya? (I have physical Brahmacharya for three months now, still struggling with the mental part)
