orthostatic hypotension and lymph nodes?

[ETGuy71]

Yes Tadalafil can cause dizziness. How many mg are you taking?
Orthostatic Hypotension is certainly a possibility. Changing position going up from down position is part of the orthostatic testing.
Of course a cardiology visit is the one you should do for ruling out this.
The cardiologist will need to know all prescription meds you are taking particularly the Tadalafil.
The lymph nodes suspicion you could a actually start with a general practitioner/family practice physician. You likely didn’t do anything but aggravate the tissue you were squeezing. If he/she has a concern after exam they can refer you elsewhere.
The main thing is you’re on it and are taking steps to get answers.
