from the way you describe it and how suddenly it appeared it sounds like a Cyst! nothing to worry about, probably it was triggered by an inflammation.
I read there's a specific type of cyst for the shin-calf area , not sure exactly where yours is
A popliteal cyst, also called a Baker's cyst, is a soft, often painless bump that develops on the back of the knee. A cyst is usually nothing more than a bag of fluid. These cysts occur most often when the knee is damaged due to arthritis, gout, injury, or inflammation in the lining of the knee joint.
have it checked by a specialist anyway they could run Ultrasonography or MRI to check where it's coming from.
Thank you very much. The bulge is right between my shin and calf in front of my leg. My doctor said not to worry about it. It's probably just liquid build up. What worrys me is that he said probably. I didn't get an MRI and ultrasound because i don't have insurance. Is there another to know for sure what it is? Is there a way to get rid of it or drain it?
I'm not a Doctor but I doubt that there's anything that can pop up so quickly other than a cyst.
You should rather investigate what caused it, sudden stress of the leg, lack of exercise, muscular weakness, the cyst itself shouldn't be a problem.
MRI is not the priority I'd rather go see a specialist. you could spend money on the MRI show it to your GP and come up with nothing.
