A chronic, non-healing wound is one that does not heal in six to eight weeks with traditional wound care. More than 5 million Americans suffer from non-healing wounds, which can cause serious infections, illness and loss of a limb.
Symptoms of Chronic Wound
- Persistent, increased pain in the area of the wound
- Discoloration of the wound near the edges of the wound – often a dark or bluish color
- Increased drainage from the wound
- Redness or swelling around or spreading away from the wound
- A foul odor coming from the wound
Muscle strain — or muscle pull or even a muscle tear — implies damage to a muscle or its attaching tendons. Putting undue pressure on muscles during the course of normal daily activities, with sudden heavy lifting, during sports, or while performing work tasks can cause muscle strain or damage. Muscle damage can be in the form of tearing (part or all) of the muscle fibers and the tendons attached to the muscle. The tearing of the muscle can also damage small blood vessels, causing local bleeding (bruising) and pain (caused by irritation of the nerve endings in the area).
Muscle Strain Symptoms
- Swelling, bruising or redness, or open cuts due to the injury
- Pain at rest
- Pain when the specific muscle or the joint in relation to that muscle is used
- Weakness of the muscle or tendons (A sprain, in contrast, is an injury to a joint and its ligaments.)
- Inability to use the muscle at all
