Hi again,
I have tried to post this response a couple times but it didn't work, so here I go again. This is extremely long, so I apologize.
Congratulations on being pregnant. You pregnancy sounds like a great alternative to "obsess" on. Maybe everytime you feel the stress of wondering if you have ALS, just redirect your self to do something toward being a mother....like reading about your pregnancy, planning a baby shower, preparing the room or reading parenting books. I have three amazing kids and I feel blessed every day that I can tuck them into bed at night and hear their sweet little voices.
Obviously there is nobody on this forum who can predict if your symptoms will become ALS, and it is a complete waste of time to focus on that becoming a reality. If your doctor & your husband think you are "obsessing", then for now, I would focus elsewhere unless you have some disabling symptoms. It seems you are functional with your body, so why not just enjoy the ability to do the things your body will allow you to do? If you have a tendency toward hypocondria, then you may develop symptoms if you focus on it, plus stress makes people so unhealthy your baby doesn't need that. The mind is very powerful, so use it in a way to try to make yourself better.
As far as I go, yes, I have been concerned about ALS as well as Lyme and I am routing for neither. I have had the twitching that has now slowed to mostly my stomach, right leg and left forearm/hand, accompanied by cramps in my hands, arm, upper arm and legs. If you had these cramps, you would definitely know you had them. They are so bad that when I go up our short flight of stairs I have to go down on my knees because they ache so much it almost feels like a charlie horse. I just try to fit my "going onto my knees" to take a minute to talk to my little ones while I rub my legs or seem like I am actually doing something so it is not a big production. I have dropped at least a shoe size on my twitching side, and also have a toe that no longer functions with the rest of my foot. This is also very livable. My biggest issue is that I have had such difficult with eating that I lost 12 additional lbs (on top of the 20 or so I lost in the last year and a half without trying) because it is so tiring to eat because my tongue actually is fatigued to move the food to the back of my throat. Is that an ALS symptom? I have no idea, but the fasciculations in my throat area were so strong for a period of time that I think it may have just worn those muscles out. I have a heavy feeling of breathing, but instead of feeling fear like I used to, I just make myself breathe and at night when I am falling asleep I just hope I fall asleep so I don't have to think about it. So, my point is that I have a few symptoms and still hoping I do not have ALS, despite some symptoms. I try to volunteer in my kids school and stopped constantly talking about it to my husband and concentrate on being healthy and doing what I can to sometimes just get through the day and make food go down my throat. It sometimes is hard, but I had my GP and my neurologist tell me it is probably a virus, so I hope it is a virus and will soon go away. I had an EMG, is was negative. I did a lyme test..negative. I tested for electrolites, magnesium, calcium and they are fine. My MRI is clear. My speech is inconsistently slurred, which I noticed, and then a friend of mine who is an ER doctor also noticed although nobody else seems to...which is great if you ask me. My ANA, Creatin, SED rate is good, tested my Acetylcholine ...good, CBC...good except carbon dioxide level is out of range, Cardio CRP..good...my muscle with all the twitches and most aches is dented and palm also. I have had my thyroid ultrasounded to see if that is what is blocking my throat and the ENT look inside and they have found nothing..... I had a clean EMG/Nerve conduction test SO FOR NOW, I dO NOT HAVE ALS. That is what the doctors say, so there is NOTHING ELSE FOR ME TO DO! As long as I am mostly functional I am concentrating on gaining the weight back and going about my life other than I do check this board because it is not completely impossible, but DON"T LET FEAR OVERRIDE YOUR LIFE... There are a zillion people on this site that would give anything to trade you bodies if all you have is twitching and fib symptoms, so go put your energy into you and your baby. If you have cancer, ALS or diabetes it is going to eventually show up, so why waste this precious, PRECIOUS time when your body is still working and you have loved ones that need you. If there is an issue in a year, deal with it in a year, not now. I think of Jaime and Momma and they struggle daily just to keep up so TRY...PLEASE TRY TO CONCENTRATE ON the important things for now. I think we all hope that "this too shall pass".
