Since how long are you having these symptoms?
Do you have any other problems such as any bowel problems?
Has the texture of your skin changed a little?
Have you had any tests or been to any doctor?
Do you have any other medical conditions?
Are you on any medications for anything?
Please let me know.
Have you experienced any fever?
Have you had a thyroid function test recently or in the past?
With your feeling of cold and shaky in your legs and weakness, it does seem likely that you have some sort of a viral infection that is causing your symptoms
You should try drinking warm fluids, take analgesics like tylenol two tablets as required three to four times a day
I think that your symptoms should settle in due course of time as the viral infection takes care of itself
Sometimes viral infections can present with minimal symptoms
and they just go away in a few days time
If your symptoms persist I would like that you should have your thyroid function checked
because a low functioning thyroid can cause one to feel cold like you are doing.
It does not sound like anything serious
Yes that is the right way to go about it
