I posted this yesterday but with inaccurate information. I currently for the past few months have been having pain in my Tibia it seems. The pain is deep and very localized. First I thought it was a bruise but I realized there was no visible bruise and plus the pain has got worse. Mostly when I bump it right, it hurts very bad. Usually I dont notice it much walking around. However the past few weeks to month the pain has been increasing. Its still in one spot but I feel it sometimes just sitting still or even aches when I am walking. Pressing the area causes the pain to feel worse. Any ideas? I am 17 year old male btw. FYI: not involved in any sports right now either. Just trying to get more opinions on what people think. Thanks!
thanks for the info so far. I am just wondering what could/would cause some sort of injury to it. I have not been involved in sports for a few years now. One thing that concerns me is I feel like a slight lump on the tibia.

somethin could be wrong- i wouldnt automatically jump to the "cancer" conclusion though-
go see a dr- get a blood test- maybe they can do xrays or MRI or CT to see if there is somthin they cannot see-

Go see a doctor as soon as possible, especially if this is a detectable lump. What you describe is classic signs of sarcoma. A sarcoma can occur in the bone or in the soft tissues such as the ligaments or muscles. Only a doctor can determine what is going on. It may not be anything, but the risks are too great to rely on that thought. The doctor may order blood work, scans, and possibily a biopsy to determine exactly what this is. Don't put it off.

What is a soft tissue Sarcoma?

It could be many things, such as a shin splint, tendonitis, etc. You should go to the doctor for an x-ray to solve the mystery.

This has been going on for a few months, steadily getting worse and you haven't seen a doctor? I wouldn't worry about it being cancer. You could have a bone "splint" or it could actually be a muscle. Go see your doctor.

Don junp into conclusions yet. many things besides cancer can casue those simptoms.

Some times people have hairline fractures: they are micro fractures in the bone that are hard to see, they can be from an old accident or overload.

It can be any things, so go to see a doctor and you will feel better. Dont wait to get it worst. A simple X ray can tell you if there is something wrong.
