Ich habe seit 2 Monaten Schmerzen im Trapezmuskel, was soll ich tun?

i fell down before 2 months . i’ve been felt pain in trapezius muscle for 2 months , i consulted doctor few times and i got x-ray too , but there is no problem in x-ray and i took tablets for a month but those didnt work .what should i do?

get gp to book ultrasound or mri scan to check if any tissues are damaged
