Certain conditions may trigger additional production of blood cells. When the oxygen content of body tissues is low or the number of red blood cells decreases, the kidneys produce and release erythropoietin, a hormone that stimulates the bone marrow to produce more red blood cells.The bone marrow produces and releases more white blood cells in response to infections.ertain conditions may trigger additional production of blood cells.

A Painful Armpit Lump may be Caused by Shaving or Deodorant. Although a painful armpit lump may have many causes there may be a very simple explanation for your condition. âCysts and infections on the surface of the skin of the armpit may be caused by shaving or use of antiperspirants (as opposed to deodorants).
Common symptoms of an armpit rash include itching, small bumps on the skin, redness or darkening of the skin, flakiness, pain and increased odor. More severe armpit rashes can cause dryness, cracking, pain and blistering of the skin, leading to fever in some cases. Several factors can cause your armpits to break out in a rash. Some common causes include improper shaving methods, excessive use of chemical-based products, excessive sweating, regularly wearing tight and synthetic clothes, exposure to a hot climate, friction and poor personal hygiene.
