Brief Answer:
The cracking sound from cracking knuckles is from gas bubbles

Detailed Answer:
Hello,

The sound that you hear from cracking knuckles is actually gas bubbles in the joint fluid which collapse, causing that distinctive sound. This does not normally harm the joint or cause any long-term problems.

I'm not sure what you meant by "trans to the knuckle", if you can explain that more I would be glad to discuss it further with you. I hope that helps, and please do let me know if you have any other questions about any of that.
Thanks.

Brief Answer:
I would not worry

Detailed Answer:
If it were me, I would not be particularly concerned about this, I would just make sure to clean the wound and watch it for any signs of infection; if not, then I would not be worried. I would also make sure you are up to date on tetanus vaccination, but it is not something I would give too much thought about.

Please let me know if you have any other questions, I'd be glad to help any way I can.

Brief Answer:
Onychomycosis

Detailed Answer:
Yes, it does look like your toenails have a fungal infection, also known as onychomycosis. Since it looks like multiple nails are involved, the treatment would probably be antifungal pills, which need to be taken for a long time, 12 weeks. So I would make sure to let your doctor know about this next time you see them so you can be started on treatment.

Answered by Dr. Aaron Branch (17 hours later)
Brief Answer:
The toe itself does not look infected

Detailed Answer:
The toe itself does not look infected, is it painful there? Is it red and swollen? If so, the fungal infection may have spread from the nail to the skin, which would also be treated by the same treatment. If you do have any pain there, I would try to see your doctor sooner rather than later.

Brief Answer:
Shoulder separation

Detailed Answer:
A shoulder separation, which is a sprain of the acrioclavicular joint, is more common in younger patients, and usually seen after a fall landing right on the shoulder. If you are older (40 years and older), rotator cuff injury or arthritis would be more common. It can be hard to say for sure without an examination, so if it has been bothering you for a long time, I would recommend seeing your doctor, and they can help confirm the diagnosis, and often a steroid injection and physical therapy are very helpful towards recovering from shoulder pain.

Please let me know if you have any other questions, I'd be glad to help any way I can.
