did i damage my vocal chords

hello, im having a little trouble yelling or singing loudly. before, i used to yell and sing loudly for as long as i could without any problems, but now when i try to do that it feels like my throat gets fatigued or i have a bit of disconfort. speaking in a normal volume i have no problem with. All this began when i tried to lift a really heavy object and as i heaved i flexed my neck muscles with too much force. thats when i felt the change. its been a year now and im wondering if i may have damaged my vocal chords or something? i guess you can say my vocal chords feel 'weaker' from this. i dont know for sure if its my vocal chords and i havent gone to the doctor becus i dont have insurance and its not something that causes me pain or disconfort doing everyday talking, but i wish my voice was like before when it could be loud without disconfort. i hope anyone has some idea of what it could be. thank you for your help:)

here is a site i think might be helpful.. i refer people to other sites because its easyer for you to look through the symptoms and see lists then it is for some one to tell you what you have.. personaly if i eat/drink dairy i cant yell.. and sometimes just by the way i sleep ( im a stomach sleeper.. with my chin proped up on pillows) i have issues talking the next day.. it is quite possable that you did damage your vocal cord.. just check out the site.. its got a good list of vocal cord problems.. :D hope i helped.. feel free to msg me if you need more help

google "NPR dysphonia" and you will hear a story similar to yours, relieved by massage.

I forgot to mention, that the reason for this is that sometimes, when you injure a muscle, it develops "muscle memory" and stays at that level of contraction until you relieve it with massage.

i am still able to make loud sounds/yell etc, but when i do i feel disconfort, sort of like a sore throat. before the 'accident' i didnt have any disconfort whatsoever. thank u for the links btw
