Hi, my name is Tony ,I m 38 years of age I am on levothyroxin for thyroid , paroxetine and clonazepam for anxiety. Here recently I started testosterone treatments because the last 5 years I have had no energy, test scares were 231 and next day 132 . My question for you is , after first injection I have been having painless head throbbing and at times light headed . Is this normal , what is it, and what should I do?
