[|Human|] I have a large lump on my inner thigh. Its soft but around it is hard. It usually comes up when I have my menstrual cycle & then disappears. This time its painful. It has no color and its warm to the touch but not hot. I want to know what it could be.
[|AI|]  Hello! Thank you for the query. Its is really hard to give precise answer not being able to see it. But from your description it sounds like varicose vein. However, other soft tissues lesions like a cyst or lipoma are also possible. With varicose vein there is a risk of veins thrombosis. Especially if you take any contraceptives or due to injury. Hardness and pain can be a symptom of such thrombosis. The best way to find out what are you dealing with is to perform an ultrasound of this lump. Hope this will help. Regards.
