Acid reflux is when some of the acid content of the stomach flows up into the esophagus - into the gullet, which moves food down from the mouth. The stomach contains a strong acid, hydrochloric acid, to help with the efficient digestion of food and to protect against undesirable microbes such as bacteria.1.
Grade 1 - a minor tear of the muscle (10% of the muscle fibers). You may be able to continue your activity because the pain is minor twinge in your shoulder. The shoulder muscle feels achy and tightness for two to five days after the injury, recovery for healing is 7 to 10 days. Grade 2 - partial tearing of the deltoid muscle (90% of the muscle fibers). You will feel sharp pain and minor to moderate swelling of your shoulder. Lifting your arm to the front, side or back and carrying a small load (carrying a bag of groceries) will cause pain and may be difficult to do.
A typical episiotomy or second-degree tear which involves skin and muscle, requires stitches and usually heals in two to three weeks. (The stitches dissolve on their own during this time.) Some women feel little pain after a week, while others have discomfort for a month. If you have a more serious tear that extends to the rectum (a third-or fourth-degree laceration), you may have pain and discomfort for a month or even longer.
