Hi,
Weakness in the hands and feet can be due to
hypokalemia,
dehydration,
electrolyte imbalance in the body. Upper sharp backache can be due to improper posture,
muscle strain, gastritis, injury or sprain to the ligaments or discs that support the spine. Maintain proper posture, stay well hydrated, take ORS, juice and soups. Eat healthily, exercise daily.
However, weakness and fatigue, upper body pain, sweating, nausea, chest pain can also be due to developing coronary artery problems. Visit ER, get physically examined and have lipid function tests, urinalysis, CBC, X-ray, Ecg, echo, stress tests and imaging tests done if required. Get evaluated, get treated. Take fiber in diet and plenty of water, avoid
constipation. Take Omeprazole when pain, take care.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K,
