Thank you for replying - it is outer side of pelvic area (upper outer part of right thing close to pelvic bone. I don't remember hitting it there. Felt a lump when touched under skin but could then see it on external almost like a swelling from a bite or a spot. but felt hard in side like proper lump. looked slightly bruised at that time. I tried squeezing the lump inside and sounded like it popped but only saw blood (sounded like it burst). After that have had dark blue/red bruising last night. When I squeezed it it was night before last. I also have very aching left leg but this is re-occurring aches on calf and front upper thigh sore to the touch.
