Spectrum, you know your body better than anyone. You realize the difference between "good" and "bad" pain concerning exercise. Your only mistake was believing that this woman was a credible "personal trainer and physical therapist". After you informed her that you' ve just recovered from an abdominal tear as well as having an old back injury, then this unprofessional woman proceeded to give you horrible advice based on her very limited experience. As a result, you received a lump in your back due to swelling from an irritated muscle. Both your doctor and surgeon advised you that this unprofessional "trainer" was practically guilty of malpractice.
You need to get a lawyer and sue this unprofessional woman for malpractice and report her to appropriate medical board in your state. Also, seek monetary compensation for any possible treatment in your recovery. Hopefully, that wretched GYM will be shut down so that no one else may suffer any injuries.
As for your wife, you should remain strong and defend your position about your stance on this alleged personal trainer. Keep reminding your wife that the people at this GYM are only friendly with her because she' s given them over a thousand dollars. Warn your wife that she shouldn' t allow this unprofessional woman or that despicable GYM come between your marriage. You (her husband) comes way before some trainer and a GYM.
Hope this helps. Peace!
