Do not stop drug without doc's consultation...
It is true that drugs prescribed for high blood pressure
can cause erection problems. However, I strongly advise not to stop taking such drugs on your own as your blood pressure might spike especially during physical activities including getting an erection.
I suggest to discuss with your doctor about your problems with erection in order to prescribe the appropriate drug without stopping the ones you take for high blood pressure.
With regards to the swollen wrist, it might be related to arthritis
damages to the wrist joint. The small blister
in the middle of your palm and having itchy palm and eyes, could be related to allergy
reaction. Can you please provide a photo of the small blister in the middle of your palm in order to assist you further?
