Huge very dark purple bruise right thigh discovered 2 days ago and is getting bigger, no pain or tenderness feel a small knot under skin?

Bruise: You don't remember bumping into something? A large bruise without trauma is unlikely. The knot you feel is probably a blood clot under the skin that will dissipate on its own. The medications you listed should not cause your bruise. It will look worse before it looks better. If you think it was indeed spontaneous, you should really have your doctor check a CBC on you. ...Read more

Rash. Lower leg. Started as small knot under the skin/ turned into 3 pinkish bumps. Itches. Haven't scratched. Now 6 inch area. Skin looks very burned?

Rash: This may have been an insect bite with an allergic response or an area of contact dermatitis from something that touched your skin. Apply cortisone cream, but if redness spreads and burning persists, an infection of the skin(cellulitis) may be present and requires antibiotic treatment(pills and cream). Your physician will advise you. ...Read more

Old scar site?: A small lump in the facial skin, that may dimple, may be an old scar from past trauma (children get hit with lots of things over the years, especially in sports, and from bumping into doors or furniture). A pediatrician, a dermatologist, or a plastic surgeon can look at it to offer a diagnosis. ...Read more

What can cause hard movable knots under the skin? My son has these on his face... Some small and large.

What can cause hard movable knots under the skin? My son has these on his face... Some small and large.

Some thoughts...: They could be cysts, little fluid filled sacs, that are generally harmless but sometimes could become inflamed. It'd be good to have your son's doc take a feel of them - don't need to have him go to an urgent care or ed, but just a regular visit, especially if they've been there for a long time. ...Read more

I hit my head on a gate latch while bending over to pick something up. It got a small knot which is now squishy. Should I be concerned?

I hit my head on a gate latch while bending over to pick something up. It got a small knot which is now squishy. Should I be concerned?

Probably not: If you did not pass out, do not have severe headaches and feel normal as far as mood then it is probably just some bruising under the scalp. It should resolve in a week or so. If you did lose consciousness or if you are having severe headaches, visual changes or mood changes see a doctor right away. ...Read more

Fight Of The Century: Here is a perfect opportunity to tell friends you got jumped by six thugs on the street and fought all of them off and walked away with nothing but a small bump on your head. I suggest this because I have every confidence you'll be OK. But...if the headache keeps getting worse or you start vomiting or your vision gets blurry,things like that,get someone to take you to the ER. Otherwise use Tylenol (acetaminophen) ...Read more

My 8 year old just hit back of her head on the corner of the porcelain sink. She has a small knot and is tender and painful. Will she be ok?

Yes: As long as she is awake and alert, she should be fine. If she begins to cry, complain of pain, develop an inability to touch her chest with her chin without exquisite pain, or develops problems with speech, walking, loss of use of part of her body, go to the er. If you have any concerns by morning, call her pediatrician. In fact, you may wish to do that now. Injury is insignificant by descriptio. ...Read more

Hello this is embarrasing but the inside of my buttcheeks is turning a very dark colour and theres small bumps that feel like knots under the skin?

Hello this is embarrasing but the inside of my buttcheeks is turning a very dark colour and theres small bumps that feel like knots under the skin?

Tricky: without an exam, I can only give general information and inflammation generally causes increased pigmentation/scarring. The areas of the body that have a lot of moisture, irritation, rubbing and germs can get infected and have abcesses that are quite serious and need minor surgery or they just get (much) worse. cannot say in your particular case, but generally true. ...Read more

Small blueish knot in vein i can feel bt doesn't realy protrude frm skin it has gotten a lot smallerdoes thatmean its goingaway or movinsomewhere else?

Not to worry: It will either go away, or remain, but in either event: does not seem serious. Superficial vein, not the type that if it does "move somewhere else" would cause problem. Deep vein thrombosis is a worry, but does not come from these superficial visible subcutaneous veins. ...Read more

I have a small bb size knot (actually feels like a small bb) under my skin on my penis, what could it be?

Cyst or other: Hello mikek, a small bb size knot is generally a benign cystic lesion as a result of trauma, blockage of ducts, or inflammation. Rarely, it can be a malignant lesion. I would advise having a physician lay his or her hands on the skin of the penis itself, sooner rather than later. Hope that helps. ...Read more

I have a swollen knot above the middle of my right eyebrow.Hit my head hard there 9mnths ago..It's small, but ugly. Advice?

Have it checked out: When you hit your head, you may have had bleeding there. If it formed a blood clot, it can leave a residual knot on the surface of the skull which you feel as the small knot. Hard to say whether it will eventually flatten out or not. There are also other things it could be. Have it checked out by a surgeon. ...Read more

I have been also experiencing burning sensations in the back of my head. I noticed a small knot as well, maybe a cyst, ? What is this sinusitis?

I have been also experiencing burning  sensations in the back of my head.  I noticed a small knot as well, maybe a cyst, ?  What is this sinusitis?

Probably not: Trauma (blow) to the region would give you a bump. Other causes can include inflammation, tumor (most likely benign), but it does not sound like sinusitis. Consult your pcp. ...Read more
