Oh Sweet jebus...i guess this is why my therapist tells me not to come on this forum I have no idea what you guys are talking about and I am not gonna click on that link (Im not, im not!) but I've had this 10+ years, pretty sure I have some sort of autoimmune PNH as it disappeared completely during two pregnancies (immune system dampened) and has come back since....but please tell me I don't have to worry about a cancer element now? I couldn't handle it. This daily twitching aching shaking merry go round is enough to contend with!! I went to one neuro in 2004, emg with fascics, otherwise clean, BFS diagnosis, off you go. Never been back. I want to 'let it go' and finally move on with my life, over a decade later!!! I also want to sleep tonight...I'm so silly I come here for reassurance when ive had a bad day of symptoms or a new weird symptom, read something like this and im off sprialling! anyone else like me with this forum? It's like im playing with fire!!_____________________________________________________________________________________________________________________________________My intention is certainly not to create fear! If it does, we are easily spooked (I know, we are, part of this crap is the exaggerated startle response). I believe in order to conquer these fears we have to look them squarely in the eye and investigate by putting it to rest. Not by extra EMGs, but investigating the other known causes? How many of us theorize forever about potential causes without looking into this one that is already documented?? Is that why this subject is avoided? Is the only thing you worry about ALS? It seems that is all that is on this board, is ALS worriers. Then they get shamed for causing fear or for worrying or being anxious. But if anything else is brought up, it is ignored. Or shamed, or misunderstood because everyone is focused on ALS. There is nothing that can really be done about ALS, no real benefit to catching it early. Fact. However, there is some benefit to looking into other causes of twitching besides ALS! Especially if you don't have the health anxiety history, or even if you do, in order to move on. Especially since PNH is a very, very early symptom of worse things that can be caught early. One of these studies says the cancer outcome is better for folks with PNH paraneoplastic because the immune system is exerting powerful response and antibodies against it. Why would we not want to know this? I am pretty sure I have some kind of autoimmune thing also! When I was pregnant, I had an immune system response, my body recognized the attached ovum or whatever as a foreign invader and I had a rash for a few weeks. So, I think my body recognizes foreign things. The link isn't all bad news. One of them is a very recent study and makes this crap treatable!! Yes, I am like you...but the ALS fear is a bit irrational after having been cleared. Hard to shake, I know. Part of PNH seems to be And a cancer fear after 10 years is also irrational. Sorry, but it is. But maybe, just maybe, you have an immune reaction to a benign tumor. Do you not want to know about it? There may be a cure? The wikipedia article on PNH says 20% are paraneoplastic. Easily available information. No one mentions it.
