It helps Raynauds: Raynaud's symptoms are caused by constraction of peripheral arteries. Cessation of smoking is the most important process. Control blood pressure and treat hyperlipidemia to prevent artherosclerosis. Prophylactic measures including gloves, avoiding cold contact, etc.

Block constriction: Calcium channel blockers, especially Nifedipine treat raynauds by helping to block constriction of the small vessels of the hands and feet thereby improving the blood flow to those areas.

A 38-year-old member asked:

How long can a fractured pinky finger knuckle/joint take to heal?

Many months: The crack in the bone itself heals in 6 weeks, but the swelling, stiffness and pain can last for many months. That's because it involves a delicate joint and because we can't help but use our fingers throughout the day and that keeps it aggravated. If your symptoms are still beyond what you'd expect, consider getting checked for a torn tendon.

4-6 weeks: Most hairline fractures heal rather quickly. That said, some fractures seem to take their time and other still will not heal without some "help". Most toe fractures that are not displaced will heal uneventfully, and within 4-6 weeks.

Blisters under: Toenails are quite common in sports participants. If you're able to drain it, apply a topical antibiotic and wrap it in a band aid, that's about the best you can do short term. You might want to check on the size of the soccer boots. If too small, they can be making things worse. Also, i hope the coach/trainer has them wearing running shoes for the pure running workouts.

She might try wearing two pair of socks on each foot and see if that helps. This was something I was taught back in high school by my coach and it worked for me. ( to prevent the blisters, not treat them.)

A 35-year-old female asked:

My ring finger on my left hand hurts really bad on the knuckle. It has a knot on the side of it. Could I have possibly tore a ligament or something?

Several Options: If you recentry injured the area of concern, then a tendon injury is possible. If not. You could have developed a ganglion cyst which tends to be common in the wrist and hand. I would have a physician examine it to find out what would be the next step.
