Hi Welcome to Health care magic forum.
You are having tickling, and itchy sensation in the
kidney area. If it is out side may be the
skin infection. If from deep in side, it may be related to the ascending and descending
colon irritation, lastly may be due to gastric irritation.
Stopping the alcohol and consulting the doctor are different things, so go on reducing the alcohol till you stop completely.
Besides you can consult a surgeon for diagnosis and treatment. You may need to have M.R.I, for diagnosis.
Avoid taking milk, milk products, wheat, and barley.
Take more of green leafy vegetables, pulses, sprouts and
protein rich food to support the medicines.
Wising for a quick and complete recovery. Thank you.
