While being treated with the machine for the first time I felt dull heart sensation which I didn’t think anything of - why would you. My osteo then said after “it uses the same waves of those used in the heart” or something like that!! I then went home and l over 24 hours had this annoying uncomfy dull chest pain over the heart area. I am now in the emergency department local hospital had my ecg and now a blood test for possible heart damage!! It’s not been a good experience for me and I think this is all a direct result of the machine! AVOID. PLEASE let me know if you know what’s going on I’m so worried.
