question: I am Neeraj and 42 years of age. Since last 15 days, I get a lump/ swelling generating on my right side of forehead. It stays there for an hour or so and subsides gradually, however leaving a feeling of heaviness above my right eye. This has happened 2 times in last 15 days. Earlier there was none of this symptoms. Last time it happened when I completed my smoke in my Car. Could that be a reason. What may be this and what can be the possible course of action. How it is caused. Worried if this is something serious. I am on constant watch, when this happens and still diagnosing the reason which aggravates it. Pls guide
