In general, you should have any lumps that last more than a week or two checked out by your vet. However, it's worth noting that small lumps that are not growing, oozing anything, or bothering your cat are unlikely to be dangerous. If a lump appears suddenly and grows noticeably, take your cat to the vet at your earliest convenience. Some lumps will be entirely harmless. For instance, hard tissue that forms at the site of an injury or after a surgery is most likely simply scar tissue. However, if a lump ever seems to bother your cat or seems infected, have it looked at right away. Your vet will likely be able to determine whether a particular lump is fluid-filled, such as an abscess, or is solid, such as a tumor or cyst. However, they will not be able to determine whether a tumor is harmless or dangerous without doing tests. They will likely need to use a needle or scalpel to remove a small amount of tissue from the lump and test it in a lab. Note that their initial tests will be quick, easy, and safe. They can likely be completed while your cat is awake, and will cause little to no pain. Your vet will recommend a biopsy if they are not able to determine the cause of a lump through initial tests. Your cat will be anesthetized so that part or all of the lump can be removed. This is worthwhile, as it allows your vet to get a definitive diagnosis on the cause of the lump.

Q: Keyed drill chucks do not typically thread onto the drill. Instead, the chuck's tapered end inserts onto a matching spindle. Look at the gap between the chuck base and the drill, and you should see this spindle. Measure its diameter. This is a cheap, two-armed wedge. Choose one with a gap between the two arms larger than the spindle diameter, but as close to it in size as possible. If you're in a hurry, skip to the end of this section for another method. Position the two arms of the wedge around the spindle in this gap. Hammer the thick end of the wedge until the chuck pops off the drill. Clean and degrease the tapered portions of the spindle and chuck. Place the chuck on the spindle and retract its jaws completely. Place a thin piece of wood over the chuck nose to protect it, then tap the chuck nose with a mallet until it fits securely onto the spindle. If you do not want to go out and buy a wedge, it may be possible to remove the whole spindle instead. This will only work if the chuck has an open center, allowing you to access the spindle beneath. Here's how to do it: Open the chuck all the way. Place the chuck above a pair of vise jaws, with the spindle hanging loose beneath it. Place a metal punch through the center hole. Hammer the metal punch until the spindle comes off the drill.
A: Measure the diameter of the spindle. Buy a chuck removal wedge. Insert the wedge between the chuck and the drill. Hammer the wedge in. Insert a new tapered chuck. Remove the entire spindle.

Article: Plain rubber bands tear and split your hair. Using heat severely dries your hair, which can cause split ends or frizz. Air-dry your hair whenever possible. Before using any heated cosmetics, you should apply heat-protection serum to your hair. Heat-protection serum will not only protect your hair cuticles, but it can also give your hair a healthy shine. This is one of the easiest ways to end up with dry frizzy hair, as constantly washing your hair can strip your hair of its natural oils. Although it's okay for those with short hairstyles to wash their hair every day, people with longer hair should consider washing your hair less frequently. People with shoulder-length hair, should wash their hair every other day; those with hair longer than that should wash their hair every third day.

Use fabric-covered hair bands to tie your hair. Avoid heated cosmetics. Don't wash your hair every day.

Article: Although chlamydia often presents few symptoms in its early stages, it's important to be aware of any symptoms you may exhibit. Consult your doctor for a definitive diagnosis if you notice any signs of chlamydia, especially if you've engaged in unprotected sex. Both men and women can contract chlamydia and repeat infection is common. The early stage of a chlamydial infection often has little symptoms and even when signs are present, usually within 1 to 3 weeks after infection, they may be mild. Common symptoms of chlamydia are: painful urination, lower abdominal pain, vaginal discharge in women, discharge from the penis in men, painful sexual intercourse, bleeding between periods and after sex in women, or testicular pain in men. If you experience any symptoms of chlamydia, including discharge from your genitals, or a partner has revealed they have chlamydia, make an appointment to see your doctor. She will run tests and confirm a diagnosis and develop the best treatment plan for you. Tell your doctor about the symptoms you're experiencing, signs of chlamydia that you've noticed, as well as if you've had unprotected sex. If you've had chlamydia in the past and are experiencing a recurrence, contact your doctor to get a prescription. If your doctor suspects that you have chlamydia, she may order further medical examinations or tests. These simple screenings will help definitely diagnose the sexually transmitted disease and make it easier to develop a treatment plan. If you're a female, your doctor may swab the discharge from your cervix or vagina and submit the sample to a laboratory for testing. If you're a male, your doctor may insert a slim swab into the opening of your penis and swab the discharge from your urethra. She will then submit the sample to a laboratory for testing. If you've engaged in oral or anal sex, your doctor takes a swab of your mouth or anus for chlamydia testing. In some cases, a urine sample may detect a chlamydia infection.
