hello, i am a 14 year old girl andi have a question,, think i may have becker md, but i dont know... i have recently been diagnosed with supraventricular tachycardia (a fast heart rate) it is usually about 160-180 bpm when i am resting. i also walk on my toes (since i was a baby) and i recently have noticed that i have enlarged calf muscles (i am quite small though, like 5'1 size 0 or 1.) i also always get painfull muscle spasms in my leg muscles and i get pulled muscls alot, very easly. i am also extreamly weak. i was looking uo my syntoms on the internet and i found that i have all of the syntoms of md. also i have been to the doc because i ahve a very curved back, not like the scoliosis curve, but it curves in like towards my stomach, he told me that it is called something (i canbt remember) but i shouldnt worry about it unless it gets worse. now that is also a syntom of becker md. what should i do?? like i am very worried do u think that i have muscular distrophy??
