Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain itchy spots on the lower legs and sides of neck with
severe itching can be due to causes like
1.
Allergic reaction to any food or medication.
2.
Contact Dermatitis caused with any skin cosmetic, detergent, soap etc..
3. Hair
follicle infection or Folliculitis.
Consult a Dermatologist and get evaluated and he can do a clinical examination and can also advise investigations like Allergic tests to confirm the diagnosis..
In case of allergic reaction you can be advised anti allergics like Allegra or Levocetrizine..
Topical application of steroid ointment and calamine lotion can help..
Doing cool compresses will relieve..
Once allergen is ruled out avoiding exposure to it will relieve..
In case if it is due to Folliculitis oral and topical antibiotics and steroid ointment can help..
Hope this information helps..
Thanks and regards.
