yes, mostly the same, 'hyperreflexia' is just the scientific word for it.what I can say you about cramping knee and fasciak or throat fascics? Sometimes I have cramps in knees and ankles. last year I had to buy low hills shoes and quit high heels becasue anlke cramps frightened me as a hell. This winter I bought high heels boots again

)) so they did not make me an invalid, neither will yours do you for sure. I also had an experience of neck twitches - not pleasant but again harmless. I still take my vocal lessons and my signing had improved a lot, which probably would not possible shouldn't I be physically fit in my neck and throat musculature...A common mistake many new BFSer fall into is to consider every new cramp or twitch, or every new pattern as a threat or evolution or progression of innocent condition into sisnster one. Based on my experience and on experience of many fellows here I can say that BFS in fact has numerous but still limited manifestations. main are: sensory issues (cold/hot patches, skin burning, bugs, touching, wet senstation etc.), twitching (buzzing, worm-like feeling. pulling. bussing. moved fingers, jerks, ratcheting), discrete muscle pain, excersise intolerance, perceived weakness, crapms, neuritis like sympromes (stabbing pain, ulnar/carpal like symptomes, numbness, night numbness), rheumatoid-like symptomes (pains and even swelling of joints, morning stifness), uncertain symptomes like increased joint clicking. That is from the part of neuromuscular system. many of us also have clear stress disorder, acute or chronic obsessive or anxiety disorder, 'hypochondria' or health anxiety. Another important part of symptomes are gut related (from leaky gut to GERD, the last casuing coughing, husky voice and espophagal spasms often taken for bulbar symptomes) and symptomes of certain dysautonimia (wet/dry mouth, frequent urination, dizziness, heart palipations etc.) We also complain for hyperventilation issues (inclreased central sleep apnea episodes, very ehxausitng and even casuing some of fellows use CPAP masks, also feeling of numbness in face, toes and finers, cold fingers, lack of breath, exhausing yawning etc.), but this is anxiety related and usually goes away as anxiety level drops down. Sleep disorders , including episodes of sleep paralysis and hypnagogic hallucinations are very common.Ah, plus skin issues - itching. urticaria, neuraangioedema (alo stress related and autoimmune condition)big list but this is almost all. you may not expect that you would have, for example, bloody vomiting, or extensive dry cough with light fever, like in TB, or fangs would never grow from your fingers like in Xman

)) so, you may expect a full size circus show with the above list of symptomes and I must confess I had most of them except maybe sensory issues are rather rare for me (however I had also a few of them, some very funny). None of them disabled neither me, nor nobody here, neither will it disable you as I said above. Just try to encompass the idea that you are not dying ( I man right now becasue in general meaning we all are dying more or less) but just sick, most probably from stress and natural predisposition to that way of surviving it, and have high level of health anxiety turning every slight or moderate symptome into big one. Your mind palys a bit of tricky game with you (and with me and with other fellows), but you are not alone.
