Hello dear, loss of cervical lordosis
may be due to variety of reasons - congenital, trauma, degenerative changes, or more commonly due lifestyle problems like wrong posture, obesity, sedentary lifestyle.
Initially this condition may be entirely asymptomatic but later on it could become a serious problem as it can result in compression of nerves and nerve roots in the neck resulting in weakness or numbness
in rest of the body. Since neck connects the head with the rest of the body this region is very sensitive and variety of symptoms can be encountered like soreness of upper back muscles, headache, giddiness, vertigo
, fluctuation in blood pressure etc.
Treatment option range from physiotherapy
to surgical measures in extreme cases. Chiropractors claim to improve this condition but I am not certain about that. I would advise you to consult a good neurologist
who can guide you better about the condition and outcome.
