Have them (fasciculation) evaluated!
Clinical.... well that’s the problem. We have pain, burning, fasciculation cramps, twitches, jerks etc. But clinical weakness! Most of what I have read on this board points to most if not all not meeting the clininical weakness criteria.
As your BFS evolves you will feel the weakness among other symptoms. Right now you may be in the state where you just have not had these symptoms but you will. I had the same issue for 3 months where perceived weakness was not an issue. But now I have "weak legs" and some knee joint pain. This will move on in the near future to another location and with a new symptom or maybe an old symptom in a new location. Transient.... that's BFS.
Weakness and atrophy from my understanding is a fundamental exam point when you visit a neurologist. If a neurologist has seen you you have gotten the "Clinical evaluation of weakness." I have sought evaluation from Internist, Rheumatologist, Neurologist, Cardiologist, ENT, Neuro-Opthmologist and anyone else I could get a consult with.
It is up to you when you will accept you have BFS and that it is responsible for your pain, burning, weakness, twitching, cramps, pins and needles etc.
If I had to do it over again having the knowledge I have now this is what I would do:
I. Two neurologist opinion
II. Two rheumotologist opinions
Why would I do this? Because I have found that in these two realms you can get cleared to accept a diagnosis of BFS as solid and not of another source such as a devastating disease such as MS, ALS or another auto-immune disease such as Lupus, Lyme, Scleroderma, Fibromyalgia that overlap and have similar symptoms to BFS.
Personally I have had
III. Three neurologist have cleared me and BFS is their diagnosis
IV. One rheumatologist examined me and he said I had gotten my diagnosis.... BFS. He did not even see it fit to have lab work done?
V. Another rheumatologist I am seeing is being a lot more thorough with all the lab work. The problem is that many of the doctors I have seen before have ordered similar but not exactly the same lab work and have all returned negative so far.
If this second rheumatologist says: "No connective tissue disease." Which he already did but wanted to alleviate my concerns with subjective testing...then I will abandon my search for another cause for my symptoms. I will accept BFS and like floater said maybe get on narcotic pain killer. A diabetic does not leave his/her insulin. A person with high blood pressure does not get of his medication. Why should I?
Though I suspect your case is different because I think you acclimated your body to klonopin and essentially made you nerves lazy. After some time you should return to being normal which explains your vigorous workouts and withdrawal symptoms. This is unlike the rest of us who need a chemical boost and may never return to normal. I really think you will return too normal because your case is opposite of most of the BFS posters. You took klonopin for an unrelated problem(s) before BFS. We took klonopin or klonopin type drugs after BFS.
