hmm. is not getting sufficient rest the cause for frequented neck/shoulder aches?
if it is the cause of it, i think it may be one of the causes for my case.
because of work commitments, i tend to stay up all night doing my work. and sometimes in the process, deprive myself of sleep and also not sleeping well worrying about work throughout the night.
my mil got worried and got me a bottle of waist tonic for me to help me relieve the stiffness in my shoulders and also to help me sleep better at night.
i guess maybe i should stop worrying about work and let myself sleep early for a change. sighs.
