It seems that you are having either irritant or allergic contact dermatitis
It may be due to soap,water,grass,shoes,socks,dust,carpet,wool,house dust mite and so on.
Thorough clinical examination and history may clinch towards the culprit agent.
Blood tests should be done to rule out anaemia, DM,HIV,thyroid dysfunction
, internal diseases..etc
After identification, causing agent should be kept away.
Local application of mild steroids
with antibiotics may be helpful.
Oral anti histaminics,steroids in tappering doseand antibiotics may be taken.
But, you consult dermatologist
for perfect diagnosis and treatment.
Avoid soap, dettol bath may be taken.
I hope you got my answer.
