Hi I have had a lump in my thigh for a while which only hurt on and off. Recently it is hurting majority of the time. I have been to doctors about this and have been referred for an ultrasound since going to the doctors last week I have noticed another lump on my lower lower leg by my shin. I am wondering if I should go back to the doctors to make them aware befor I have the appointment come through for the ultrasound I have pain upto my groin and feel very tired and worn out all the time also have low vitamin d. I am extremely worried and just don't know what to do
