After going through your query I think you are having muscle cramps and generalized pain all over the body. In my opinion these pains are likely to be due to vitamins and trace element deficiency specially that of vitamin D.
I will suggest you to got following test to see cause (if these are not done earlier).
1.Serum Vitamin D
2.Serum Vitamin B12
3.T3,T4,TSH(Thyroid profile)
4.Blood sugar fasting and PP
5.Hb
Furthermore I Empirically treat my such patients by:-
1.EVION LC
2.VITAMINE D3(if it is low)
3.VITAMIN B COMPLEX AND VITAMIN C
4.CALCIUM
5.Mecobalmine
6.ANALGESICS SUCH AS DICLOFENAC
You can discuss with your treating Doctor about it.
Hope I have answered your query. If you have any further questions I will be happy to help.Wishing you good health.Take care

Hi
Thanks for posting your queryI Dr.chugh,Orthopaedic surgeon
The Cramps are caused by hyper excitability of the nerves that stimulate the muscles. They are overwhelmingly the most common type of skeletal muscle cramps. Cramps at rest are very common, especially in older adults, but may be experienced at any age, including childhood. Rest cramps often occur during the night. While not life threatening, night cramps (commonly known as nocturnal cramps) can be painful, disruptive of sleep, and they can recur frequently (that is, many times a night, and/or many nights each week). The actual cause of night cramps is unknown. Sometimes, such cramps are initiated by making a movement that shortens the muscle. An example is pointing the toe down while laying in bed, which shortens the calf muscle, a common site of muscle cramps. The cause of cramps is as following-1. Low blood levels of either calcium or magnesium directly increase the excitability of both the nerve endings and the muscles they stimulate. This may be a predisposing factor for the spontaneous true cramps experienced by many older adults. Cramps can also occur in excessive vomiting, dehydration.2. On drugs which causes excessive urination. Leading to low calcium, Magnesium, potassium level. Drugs given for asthma, angina and Parkinsonism also lead to cramps. Cholestrol lowering drugs like statin also cause cramps on chronic use.3. Several vitamin deficiency states may directly or indirectly lead to muscle cramps. These include deficiencies of thiamine (B1), pantothenic acid (B5), and pyridoxine (B6).Most cramps can be stopped if the muscle can be stretched. For many cramps of the feet and legs, this stretching can often be accomplished by standing up and walking around. Gently massaging the muscle will often help it to relax, as will applying warmth from a heating pad or hot soak. If the cramp is associated with fluid loss, as is often the case with vigorous physical activity, fluid and electrolyte (especially sodium and potassium) replacement is essential. Certain drugs like baclofen are helpful.A simple way to prevent night cramp is stretch your calf muscle before going to bed 3-4 times and each time holding for 10-15 seconds. Quinine water tonic is also useful to prevent night cramps before going to bed.I hope this information will be helpful to prevent night cramps.
If you have further query I shall be glad to answer.
Take care and wish you good health.
