What can cause major bruising above the knee (thigh) & upper leg? It went away on its own (3 weeks) on a friend of mine, could it be a silent signal?

Could be normal: It's hard to say without more information. The important thing would be to determine the history and any associated symptoms. Without any other symptoms or history, it may represent normal bruising which surprisingly can sometimes present with a severe appearance and little trauma (sometimes not even remembered). ...Read more

Is it possible to have a severe bone bruise of the tibia cause compartment syndrome in the lower thigh of the same leg.

Is it possible to have a severe bone bruise of the tibia cause compartment syndrome in the lower thigh of the same leg.

Compartment syndrome: Is not likely to move up to the thigh from the lower leg. The fascia of the muscles of the legs and arms is so tight that it doesn't allow for expansion in the crushed muscle so the swelling leads to pain and damage to additional muscle and can result in loss of the limb in extreme cases. Have it checked in an emergency room...Special equipment to measure increase in pressure in the muscle. ...Read more

I got bruising on my right side of upper leg when I was knocked down while playing soccer. It has been a week still not recover yet? What should I do?

I got bruising on my right side of upper leg when I was knocked down while playing soccer. It has been a week still not recover yet? What should I do?

Give it more time: If you are functional (doesn't hurt to move or play sports) and you're still noticing bruising, just give it more time. A larger bruise may take more than a week to resolve (and you may notice the bruise moving down your leg a little, this is normal as the blood settles).
If it's still very tender or impairing you, get it checked. ...Read more

Hit my upper leg on edge of table very hard a month ago. Had a huge bruise and pain but it's gone. Now I touch & feel a hard lump under skin. Hematoma?

Hit my upper leg on edge of table very hard a month ago. Had a huge bruise and pain but it's gone. Now I touch & feel a hard lump under skin. Hematoma?

WeAllTakeOurLumps: Yes, it could be what remains of a hematoma under the skin. That lump could be there for a few months but the body absorbs most or all of it. Nothing dangerous. Sometimes some scar remains forever but shouldn't be a problem unless you can see it and it bothers you. But, if it starts growing or begins to hurt or the skin discolors, get it checked out. ...Read more

I have a bruise on the inside of my thigh & I don't recall doing anything to cause it to bruise. It is now getting bigger and darker. Is this normal?

Probably: You might have bumped into something without realizing it and yes bruises tend to get darker after a few days before start fading away leaving first a yellowish tinge before complete resolution. If you are taking aspirin or fish oil, you may bruise easier. If this is a frequent occurrence, you need to consult your doctor to find out if you are a bleeder. ...Read more

I got a knee to the thigh which caused bruising. A couple of days later I felt some discomfort on the side of my knee. Is this cause of the bruising.

Bruising:knee pain: The knee to your thigh caused a contusion (bruise) but although this is the first damage one sees, other damage can be done to your knee ligaments, which heal very slowly and would be noticed a "couple days later". Blood from the bruise in your thigh can migrate down to your knee (gravity), and the swelling can also cause mild pain. ...Read more

Ct scan, 7 kidney stones& calcium build up in right kidney. What causes build up? Could calcium be reason 4 unexplained purple bruises, thigh itchness?

Ct scan, 7 kidney stones& calcium build up in right kidney. What causes build up? Could calcium be reason 4 unexplained purple bruises, thigh itchness?

Kidney stones: Most often renal (kidney) stones are the result of dehydration. However, some people are more prone to form stones than others. I would recommend seeing a urologist who can do a complete metabolic workup of your stones, urine and bloodwork. With that info- you and your doctor will have a better idea of why you form stones and how to prevent them in the future. ...Read more

You: You need to have a medical evaluation immediately. I am concerned that you are having more bleeding from your cyst, a urinary problem, or something more serious. Please have an immediate medical evaluation. A high white blood cell count is not typical for a ruptured ovarian cyst, it is concerning for infection. ...Read more

I fell in February of this year and got a really big bruise on my upper thigh. I can still see it slightly on my leg. I'm flying to the US in October. Do I need to worry about the bruise and blood clots with such a long flight?

I fell in February of this year and got a really big bruise on my upper thigh. I can still see it slightly on my leg. I'm flying to the US in October. Do I need to worry about the bruise and blood clots with such a long flight?

No: The bruise itself would be unrelated to the development of a deep vein thrombosis. Taking a long flight can be a risk factor for getting a clot. I would not worry about it, I would just make sure you get up or at least do foot pumps every 30 minutes and consider taking an aspirin twice a day if there is no medical contraindication. ...Read more
