For 3 days I can feel a hard pea-like element under the skin of my right upper groin. It's neither painful nor raised. And even it can not be seen by open eyes. It's only felt when I touch there. Basically, I regularly check my body by myself and I didn't feel it before. What could be this? And how to get rid of this? In addition, I say that from almost 2 weeks I have been treating with my penile glans infection and my doctor prescribed me lizolid 600 antibiotics and T-bact ointment and now that infection is healing. That's all.
