Brief Answer: Lesion in groin, more likely to be infective Detailed Answer: Hi I understand your concern regarding your skin problem and I hope I am able to help you in the same time. From the description that you have provided , it looks like you had developed a lesion of folliculitis which is basically an infection of the root of hair follicles. Such an infection is very common in the site mentioned by you. These are basically infective lesions but they tend to bleed a lot in this area since the groin region is very vascular. It is highly unlikely that you have caused any trauma to any vein since the main and the thick veins in this region all tend to very deep seated. The superficial ones do not bleed much since they quickly shrink on injury. The leg pain that you are having is basically refered pain from the initial site. So all you need to do is to clean the area properly with an antiseptic lotion twice a day and apply a topical antibiotic cream like neosporin over the affected area twice a day . You can take some oral anti inflammatory agent like paracetamol twice a day. This will help in reducing the associated inflammation , swelling and the pain as well. Hope it helps Please ask if you need any further clarifications Dr Geetika Paul
