I ve been experiencing leg pain in my inner thigh, buttocks & sometimes the back of my leg. I noticed a few days ago a lump on my inner thigh just below the groin. It hurts when I touch it. When I drive or sit @ work & get up to walk, I limp from pain.
Here you need to get it checked what kind of lump it is.  May need to under go for excision and biopsy too.  So go ahead and check it with proper. Medical treatment and based on biopsy report only we can come to know what to do next.  If it is a normal lump then will be fine in few days but if it is related to any benign or malignant lump then need to do proper management. Hope this was useful for you.  Take care.
