I refuse to take off my shirt because of embarrassment. However, there are many other reasons that cause a spurt of male breast growth. Medicines are one of them. Your list of medicines is awesome. On your list, I see digoxin and Tenormin, both of which can be responsible for gynecomastia.
Digoxin is a common heart medicine.
It belongs to the digitalis family of drugs. Tenormin is a beta blocker. Beta blockers are another large drug family. They are used to lower blood pressure and regulate irregular heartbeats. The doctor might be able to substitute other medicines for those two drugs.
