This happened yesterday evening, as i was talking to my friend and he had something for me. so, i suddenly turned to him and looked at my right side and soon after that.. i felt something wrong at my left shoulder.Yesterday i couldn't sleep so today in the morning at around 5:30 am my mom gave me a p.c.m and i could sleep for one hour. she took me to a neurologist this morning and i told the doc. that i needed temporary solution as my board exams are going on. the doc. gave me skelebenz 15 and ace proxyvon. they told me that i have muscle spazam. i want to know more about this disease and how to get it diagnosed ? please help me my shoulder pain has not reduced yet and are these medicines safe for me? is muscle spazam genetic or is this disease 100% cureable?
