Hey guys, so i've been teaching myself the trumpet for just over 2 years and getting better and better every day. but over the last few months i have noticed a slight pain in my lower right side of my stomach (just around where my belt is). It is not such a sore pain it just kind of lingers around, i didnt go to the doctor cause i don't have one. Lately i have been concentrating on pushing myself up the register concentrating on getting a good grasp of F and G (on staff), i notice my stomach muscles are definatley developing and its like ive been doing sit-ups. Just wondering if it is common to get slight abdominal pains through trumpet playing? or is it more likely my lifestyle? ie drinking etc? lol. I realise you guys are not doctors but im just wondering if it is common? many thanks in advance.
