Thirty-four yr old female. Always tired/extreme fatigue. Labs are good. Help!!! What can be the cause?

Hi my dose of escitalopram was changed from 10 to 20 mg. 2 days ago. Can it cause extreme fatigue once upping the dose and side effects? Wanna give up

If by "extreme fatigue" you mean falling asleep or not fully alert, you should discuss dose increase with prescribing doctor. Increases can be smaller, eg, even by 2.5 mg increments (break a 5 mg tab in half). This is just general info since I don't know details of your situation. Do talk to doctor. I hope this is helpful. ...Read more

Lymph nodes are basically reservoirs for debris from a virus/bacterial infection. I would encourage conservative measures for a cold such as rest and otc medications.
