Hello,
Headache and weakness may be indicative of
dehydration, low BP, low glucose level,
electrolyte imbalance of the body. You should keep your vitals normal, keep your blood glucose level, BP normal at all cost. Take ORS and water to maintain body electrolyte system. Sodium and potassium depletion causes weakness. Since you have a history of Meniere's disease you are suggested to get clinically examined by an ENT to detect any developing tinnitus or vertigo.
Get audiology test done to assess the degree of
hearing loss. Get CBC, Hb%,
urinalysis, etc done. If the reports are positive, you will be treated accordingly. For immunity you should take home made food rich in protein and minerals. Take vitamin B6, B12,
vitamin E rich food or supplements. Aswagandha is also very good for immunity. Avoid addictions if any. Maintain healthy BMI. Stay away from stress and anxiety,
Take care. Hope I have answered your question. Let me know if I can assist you further.

Dr. Nupur K., General & Family Physician
