Convinced I have ALS

Hi my name is Ashley I'm a 26 year old registered nurse. I'm sorry I'm not quite sure how to navigate this site yet. About 3 months ago I started having sensory symptoms and was concerned about MS. Had a clean brain MRI and let it go and trusted my neuro. Starting the end of September my first symptom that worried me was a feeling of heaviness in my right arm and now my right leg that has only gotten worse over the weeks. Now for almost a month I have had muscle twitching in every muscle although recently it seems more right sided and in the same muscles, as well as some cramping in my feet, tightness in my leg muscles, I also have muscle soreness and my right arm and leg fatigue at a frightening pace (ex. If I wash my hair my right arm is burning and fatigued a few scrubs in). I also have tightness in my leg muscles more so in my right. I do realize sensory isn't usual of ALS. My first neuro did a physical and said I was fine. I didn't feel fine and asked to be referred for an emg. I was then referred to another neuro who agreed my exam was fine and performed a nerve conduction study and emg. He said it was normal however he mentioned that I have polyphasic potential in one of the muscles of my right arm (which I know is not normal but he said he was still not concerned about ALS and that this was not indicative of ALS). He sent me for an MRI of my cervical spine which was normal. Needless to say I feel worse everyday and notice what I believe to be atrophy in my right thumb region and right calf which my neuro has acknowledged but kind of brushed off but it is very evident to me. I'm at a point where my family is concerned about my me mentally and I'm frustrated because I know what I'm feeling is not right. When I squeeze something with both hands I'm weaker in my right and it seems like I'm using different muscles to make up for it. I'm 3 months away from my wedding and can't focus on anything else. I asked him to refer me to an ALS specialist. I respect all of your opinions I just don't want to feel alone anymore and wish this would all go away. Im sorry for going off on a tangent but this is become debilitating not knowing. I know I should just believe the neuro but as my symptoms get worse and the atrophy looks more apparent I doubt him and I've seen post on this site of people with clean emgs later being diagnosed, meanwhile mine wasn't completely normal because of the polyphasic potentials in that muscle, although my neuro was not concerned. I work as a nurse and can still function throughout the shift, I also bartendered an 8hrs shift yesterday but my right leg and arm felt like jello after making a couple drinks. I know I sound crazy, I'm well aware of that but I so badly want to live my life with my wonderful fiance and we have so much planned for our lives, the fear of missing that is enough to drive me crazy. 

Attached are are some pictures of what I feel is atrophy.
