Hi, thanks for writing to HCM.
From your description, I suppose that you pain in the multiple joints could be related to viral arthralgia
(as you are travelling a lot exposed to different atmospheres in short intervals) which is usually self limiting.
The other possible cause could be exposure to cool climatic conditions, wherein during early morning hours all the soft tissues around the joints (ligaments, tendons, muscles) will be stiff causing you more pain to feel in the morning time.
I suggest you to do simple and gradual warming up exercises in the form of gentle stretching (which should not be painful) after getting up from bed. Before activities, gentle heating can help loosen the muscle. Apply a heat pack to the painful area prior to stretching or exercising. As a general rule of thumb, remember to heat before an activity and ice afterwards.
Local massaging with creams and gels may provide temporary relief from osteoarthritis
pain. Some creams numb the pain by creating a hot or cool sensation. Pain creams work best on joints that are close to the surface of your skin.
Hope this information is helpful. Have a nice time.
