cos my mum also got that problem
the chinese doc say her vein shifted due to my mum sleeping
posture
n she went for a few session of massage the pain n aching is
gone
for your case i am not sure is better to see one
dun stress your body n yourself
as human live to enjoy life right 
hmm.. i think my vein shifted due to my sitting position from my
office chair. 
i think not so serious to go for acupuncture for my case yet
ba.. massage is another alternative..
