welcome to HealthcareMagic
As you said you are suffering from high blood pressure
and also triglyceride so i guess you are taking treatment for both problems and you are also having hypothyroid for which you are taking thyronorm-50.Please see if you are on medicine for high BP and triglycerides as some drugs like beta bockers used for controlling blood pressure(atenolol);atorvastatin
for cholesterol and triglycerides
can cause fatigue and muscle pain
.Also hypothyroid is one of the major reasons to get fatigued.So I would suggest you to consult your doctor ;if required get tested for thyroid again and then get treated.If your doctor gives you neurobion
injections it is fine but do not take it on advise of a friend as the injection is painful and before taking it it will be better to know the cause of fatigue.
