The Itchy bruises commonly are scabies or allergy. You can take antihistamines for relieve. Apply Ascabiol lotion to the area affected after a thorough wash. Leave it for 40-50 minutes & then have a shower. Repeat this after 12-15 days. It should go away if it is scabies or due to allergy.
You are suggested to visit a dermatologist
& get clinically examined. Sometimes, itching & numbness
is due to nerve disorders. Get CT, MRI, & X-ray along with Nerve conduction tests done to detect any such developing pathology & get treated at the earliest.
Locally, you can apply ointment Hydrocortisone
in the affected area for relieve. Take vitamin B12
, B6, folic acid
with minerals for supplement.
