Hello dear,
Given the fact that there is history of diabetes & thyroid in your family, your symptoms can be attributed to Neuropathy (damage to nerve) &
Retinopathy (any pathology in the retina of eye) secondary to Diabetes or
Thyroid disorder.
Investigations like estimation of blood glucose level, Thyroid profile & Fundoscopy will be helpful in clinching the diagnosis.
However, other causes needs to be ruled out, such as:
1. Deficiency of certain nutrients like Iron, Vitamin B 12, Calcium,
Magnesium, etc.
2. Any fluctuation in blood pressure levels.
3. Inadequate hydration & nutrition status.
Symptomatic relief can be obtained with nervigenic agents (like Vit B6, B12,
Folic acid) as well as
multivitamin & mineral supplementation.
There is no need to worry, you will be fine.
Meanwhile, maintain adequate hydration, take a healthy balanced diet & avoid stress.
Wishing a good health.
Take care.
