Other possible medical conditions are listed below
Sorry for the delay in reply, which is due to difference in our Time Zones.
had probably found normal reflexes during neurological examination, based on which he had excluded GBS. If that is the case, I agree with him.
Summarizing your problems : throat infection
followed by tingling in limbs and face, soreness in thighs/legs and back, rapidly deteriorating breathing problem, difficulty in swallowing, extreme tiredness/fatigue and breathlessness during sleep.
The symptoms suggest involvement of nervous system, lungs/heart, muscles and possibly, joints.
Stiffness of jaw with difficulty in opening the mouth wide can be due to inflammation of the jaw joint (Temporo-mandibular joint-TMJ), which may- or may not- be part of the disease complex.
Apart from auto-immune diseases such as GBS/AIDP (which are less likely in the presence of normal reflexes), similar symptoms- in different combinations- are found in other conditions, such as,
(a) Lyme Disease (tingling, soreness of muscles, difficulty in swallowing, breathing difficulty, extreme fatigue)
(b) Polymyositis (pain/soreness and mild weakness of thigh muscles, back muscles, difficulty in walking, shortness of breath
, extreme fatigue and involvement of one or more joints, such as, TMJ.
(c) Systemic Lupus Erythematosus
(SLE)- though much less common in males, can have an acute onset and manifest with tingling, soreness of muscles, shortness of breath, fatigue.
(d) Connective tissue
diseases, such as, Ankylosing spondylitis
which can- in a few cases- present in an acute form, with some of the symptoms similar to those of yours; and,
(e) A viral infection (such as, Cytomegalovirus or Epstein Barr virus) with prolonged complications (called post-viral asthenia) in the form of extreme fatigue, soreness of muscles, shortness of breath.
Since your neurologist has apparently excluded abnormality of the nervous system, I would therefore suggest that you consult a Rheumatologist
and apprise him of the possibilities mentioned by me. He will order various specific tests to exclude- one at a time- the above-mentioned disorders, and detect the exact cause by way of exclusion. It is NOT possible for me to do so online, without examining you thoroughly.
