What u experiencing r somatic features of depresion only....there is possibility that ur depression
is not under control or some tense thing/exertion happened recently causing u this problem.
If u not consulted to ur psychitrist recently pls consult him again and explain features u experiencing, there is solution for this and he will definately guide u.
Till then try relaxation exercise...Yoga
,maintain ur meal time strictly,avoid hypoglycemia
,maintain ur sleeping and waking up time that will keep ur headache episode in control.
