The best thing to do is to schedule an appointment with your doctors
">primary care doctor. Testosterone deficiency is an increasingly recognized problem, and more and more men are taking testosterone, either by injection or by the use of topical preparations, to treat this problem.
Testosterone supplementation can have many undesired side effects and does carry some risks. Some of the more common side effects include acne
, stomach upset, and changes in mood. More serious side effects that require close monitoring by your doctor include problems with the liver and possibly an increased risk of prostate cancer.
I am not aware of any literature that suggests that testosterone injections can cause enlargement of the lymph nodes in the groin (the inguinal lymph nodes). However, the lymph nodes are an important part of your body's system for fighting off infections, and I wonder, since you are injecting the testosterone, if you might have developed a minor skin infection from the injections that could be the cause of the swollen lymph nodes.
Again, the first step would be to call your primary care doctor's office and get an appointment to have this looked at. In the mean time, if you have any severe pain, redness, or swelling, or fever, then you should seek more urgent attention in the emergency room.
