Yes, it can be if you sprained or twisted the ankle. It could also mean a circulatory/vascular issue. See a foot doctor and a vascular specialist immediately.

Yes. Athlete's foot is caused by fungus. Fungus is prevalent everywhere. Excessive moisture (i.e., shoes from sweaty feet, or exposure to wet environment) can cause fungi to thrive more and grow out of control.

Is the pain at the back of the heels or bottom of the of the heels. You could have Achilles tendinitis (if at back of heel) or plantar fasciitis ( if at bottom of the heel).
Wearing shoes that are too flat can cause strain and tension on plantar fascia (ligament band that goes from heel bone to balls of the feet). And if you wear high heel shoes a lot, then wearing flats could also pust strain or tension on Achilles tendon because of shortening of the Achilles tendon due to constant high heel use.

Weight does play a factor in certain pain conditions of the lower extremity. Also, activity levels, standing or walking or running too long on hard surfaces in improper shoes, can all contribute to pain in ankles.

Heel spur surgery is usually recommended if the heel spur itself, and not the ligament and soft tissue inflammation, is the reason for the pain. If the the spur gets too large it can become painful and wound definitely need surgical correction to remove or make smaller. It the process you will have your plantar fascia ligament cut off of the heel bone to get to the spur.

Getting rid of toenail fungus IS a DIFFICULT task. It can take 8-12 months or even longer. Fungus is everywhere and is difficult to avoid. The problem is that given the right environment fungus can grow steadily and rapidly and take over skin (athlete's foot or tine pedis) and toenails (fungal nails or onychomycosis). Fungus in the nail is more difficult to get rid of that fungus on the skin.
To start the process to rid yourself of this over growth of fungus you must change the environment in which your feet reside. Shoes are the main culprit. Fungus loves moisture, warmth, and darkness for best growth. So if you keep shoes dry and exposed to light (sunlight is best) you will prevent the growth of the fungus. Sweat from feet contributes to the moisture. That's why I recommend patient's avoid wearing the same shoes more than two consecutive days, especially shoes with fabric linings. Next, put your shoes in an environment that will keep them dry (ie in a window to get sunlight, in a boiler room or near a heat source). Next thing is to spray the insides of the shoes with Lysol, a 1:1 mixture of vinegar and water, or some antifungal spray. Do this especially if you are wearing the same shoes often. You also want to make sure you dry your feet thoroughly after a bath/shower or after soaks.
Soaking your feet in a 1:1 mixture of vinegar and water every day for 20 minutes is another way to kill fungus. Acetic acid the makes up vinegar kills fungus.
After all this, you can then see a podiatrist for topical and/or oral medications that will help get rid of the fungus. Please note, the oral medications do have some harsh side effects so please discuss these with your doctor, especially if you have social habits of consuming spirits regularly.

If you bunion keeps coming back it may be a function of poor-fitting shoes and lack of proper foot function. If your shoes do not give your feet proper support, especially arch support, then your foot is not function at its best when you are walking, standing, or running. This results in joint being mal-aligned causing other joint to move improperly.
If your shoes are constricting feet or toes or pushing toes in one way (in the case of narrow tipped shoes) then you are providing the perfect environment for bunions to never be corrected

There is no way to completely prevent warts. There are ways to avoid or minimize the risk. Such can be to avoid walking barefoot in gyms, pools, locker rooms.
OTC treatments do not work as well for getting rid of warts. See a podaitrist for better treatments of plantar warts

Yes. Treatment includes injection of a cocktail of anesthetic and steroid into the soft tissue at the heel spur location

Yes you should. Diabetics develop problems with their feet 80% of the time. You can experience diabetic peripheral neuropathy, vascular disease, and skin/toenail conditions.
Please make it your business to see a podiatrist every 2 or 3 moths. About 5 times a year is highly recommended.

You are the perfect candidate for surgical correction of your bunions.
Here are some videos of the various types of bunion procedures we can do:

The hurt is the beginning of frost bite. Wear better insulated shoes. Try wearing thicker socks or wear two pairs of socks. Try warmers, which are these gel packs that you put in shoes, gloves, or in your pocket

Yes it could be serious. Is it soft or is it hard like bone. Either way you should get it checked.
You should see and foot and ankle specialist ASAP

Definitely sounds like a problem you should not be having, especially at 18 years old. I would first see the primary care doctor. Then I would see a podiatrist next.
There could be some systemic condition or disease causing this and affecting the soft tissue or bones of your ankle joints.

Probably is. If it hurts a lot after standing up from periods of rest, it is most definitely a heel spur syndrome or plantar fasciitis.

The active ingredients in Vicks are camphor (a cough suppressant and topical analgesic), eucalyptus oil (a cough suppressant) and menthol (a cough suppressant and topical analgesic). Camphor and eucalyptus are know to kill fungus (the cause of athlete's foot) or prevent their growth.

The bunion correctors or bunion splints work like how eye-glasses work. They only work when you are wearing them. Take them off and your bunion is still there. Encourage her to go see a foot doctor, especially if the bunions are painful.

Avoid getting the dressing or wound wet. Avoid close fitting shoes. Avoid too much walking or activities that require the consistent use of your feet.

For the most part heel bone fractures do require surgery. In some cases if there is no displacement or separation of misalignment of the fracture fragments you can probably heal well being non-weight bearing in a cast for 6-8 weeks. However, in your case the fracture shows no signs of healing after 3 weeks so surgery should definitely be done. Surgery with plates and/or screws would give the be stability to the heel bone since it is taking a lot of weight when walking.

There are several cures for toenail fungus. But not every treatment will work on every person. When using topical anti-fungal medication, I encourage patients to file/rough-up the surface of the toenail so the medication seeps into the nail easier and also to put the solution or cream under the front edge or sides of the toenail.
