Hi, Thanks for posting in HCM. Considering your age, the symptoms you are complaining of like muscle / joint pains, head sweats, difficulty in losing weight and fatigue could be due to Vitamin D deficiency or iron deficiency. Hence, these conditions needs evaluation. Both of these are treatable condition and hence there is nothing much to worry about. Kindly get the following tests done to know what could be the cause. 1. Serum Vitamin D levels. 2. Serum Ionized Calcium levels. 3. Serum magnesium levels. 4. Complete blood count with peripheral smear examination. Kindly consult Physician with the reports for appropriate assessment and management. Hope the information provided is clear. All the best and wish you good health.
