Have Severe Itching On Body, Hands Are Sore And Swollen. Rash On Chest. Is It Due To Side Effect Of Blood Pressure Medication?

Antihistamines, steroids, consult internist
Detailed Answer:
Hi and thanks for the query,
I suggest a deep evaluation for a possible allergy to some specific substance be searched for. A complete blood count in search for raised blood cells called eosinophils could be helpful. Testing for an antibody called Immunoglobulin E is very diagnostic of an allergic process. Once diagnosed sources could be sought.
Parasitic infections like Filarial worms could also be responsible for chronic itches. A thick blood smear, and cutting part of the skin to examine under a microscope called a skin snip could be very useful.
A rare disease like Sarcoidosis and some blood disorders (polycythemia rubra vera due to excessive red blood cells) usually reveal themselves at times with chronic itching.
Relief could be obtained by using drugs like anti histamic drugs (Primalan, Aureus, Chlorpheniramine) and injectable steroids (Solumedrol or Dexamethasone), under strict supervision of a Doctor.
Your case should require a more holistic evaluation. I do suggest you book an appointment with an internist for a proper evaluation. Do feel free asking follow up questions in case you got specific concerns. Thanks and kind regards.
