Twiching is freaking me out

Hello ima male 22 years old and very active I teach jiujitsu for a living and I've had twiching all around my body but is most aggrisve in my right hamstring...its been happening for 6-7 days now I'm kinda freaking out and wondering if its to early to go to the doctor...I have no weakness I ran 3 miles yesterday no issue when I get home it acts up a lil but today I didn't run took a rest day and my right hamstring is really acting up...I'm also wondering if there is anyone who's had twitches like that for a while and has not had any weakness and has not been diganosed with asl...and dose muscle twiching all the time cause muscle to die always I'm very nervous and any advise would be great
