There is blood on the big toe

The most common reason for bloodshot big toes is trauma, which can easily occur when the toe is impacted or squeezed. However, bloodshot on the big toe may also be related to disease. There are many types of diseases that may be involved. If it lasts too long, we must find out the situation as soon as possible and treat it symptomatically to avoid hidden dangers to our health.

If there are blood-like substances in the nails, you should first rule out whether it is caused by ruptured blood vessels. If the nails bleed due to trauma, they are mostly fragmented bleeding spots, which will quickly turn brown in color, and will gradually move to the distal end of the nail as the nail grows. Of course, to confirm the diagnosis, you must see the diseased nail and do some relevant examinations. Due to some medical diseases, such as subacute bacterial endocarditis, peptic ulcer, hypertension, malignant tumors, rheumatoid arthritis, etc., linear or splinter-shaped bleeding may be seen under the nail, which is most common on the thumb and little finger.

How to measure your health with your fingernails

It is not idealistic to judge a person's health condition by looking at his nails. A person must have good nutrition for their nails to grow normally, otherwise some abnormal phenomena will occur, and doctors can often use this to diagnose important diseases. Here are some abnormal nail phenomena:

1. Clubbing: The nail is significantly arched upward and curved around the finger. Nail clubbing may indicate emphysema, tuberculosis, cardiovascular disease, ulcerative colitis, or cirrhosis of the liver.

2. Blue Crescent: If the crescent-shaped white mark at the base of the nail has a blue halo, it may indicate any of the following conditions: obstructed blood circulation, heart disease, Raynaud's syndrome, vasospasm of the fingers and toes, usually due to cold exposure. But it is sometimes associated with rheumatoid arthritis or the autoimmune disease lupus erythematosus.

3. Spoon-shaped nail: The middle of the nail is sunken, and the entire nail becomes flat or spoon-shaped. This type of nails is related to iron deficiency anemia, syphilis, thyroid disorders, rheumatic fever, etc.

4. Lindsay's nails: The half of the nail near the tip is pink or brown, and the half near the nail is white. This type of nail is also called bipartite nail and may be a sign of chronic renal failure.

5. Beau's lines: Horizontal grooves on the nails indicate malnutrition or a serious illness that temporarily affects nail growth, such as measles, rib inflammation, or a sudden heart attack.

6. Thali's nails: Most of the skin under the nail turns white, leaving only a small area near the tip of the nail that remains normal pink. This may indicate cirrhosis of the liver.

7. Yellow nail syndrome: nail growth slows down and becomes thick and hard; it is yellow or green. Causes include chronic respiratory diseases, thyroid disease or lymphatic disease.

8. Bleeding: If these vertical red lines appear on the nails, it means microvascular bleeding. If multiple such blood lines appear, it may indicate chronic hypertension, psoriasis or a fatal infection called subacute bacterial endocarditis.

9. Irregular pits: Many psoriasis patients have this phenomenon.

10. Rows of pits: The surface of the nails becomes like the surface of copperware hammered by a coppersmith, sometimes caused by alopecia areata. This is an immune disease that is not well understood by the medical community and can cause partial or complete loss of hair.

11. Brown or black spots: These spots, especially those that extend from the nail into the surrounding finger tissue, may indicate melanoma. They may be a single large patch or a cluster of smaller spots, and are most common on the thumb and big toe.
