Had an urgent MRI a few weeks ago after having an urgent ultrasound that showed a lump but radiologist couldn't tell what it was. I have a lump in my thigh, it's about 5cm and deep in my muscle. It's starting to cause pain, im guessing as it's growing it's pushing in a nerve? I also get tingling sensation in leg often also. It's coming up to 3 weeks since MRI. Is it right to assume that it's nothing serious if I haven't heard yet? Just asking if anyone waited a long time for results but still had a serious outcome? Thankyou!
