When you do go to the doctor ask him/her to check your levels of vitamin D and potassium.
According to my cardiologist, excess potassium and magnesium are easily excreted by the body as long as one does not have impaired renal function. IOW, unless you have kidney issues it's safe to take them as supplements. Potassium and magnesium are important for muscle stuff (and that's about as technical as I can get tonight
). I would suggest eating a couple of bananas a day for a week and see how you feel. I picked up some magnesium supplements at kroger for about $2.00.
Also, it's not at all uncommon for people in the northern latitudes to be vitamin D deficient in the winter and early spring months. Plus, with your Chronic Obstructive Pulmonary Disease (COPD) I know you have trouble with asthma and the outside air so I'm not sure how much sun exposure you're getting. You need about 20 minutes a week on exposed face, neck and arms - without sunscreen. Foods aren't fortified with enough vitamin D to make up for this. So, ask your doctor to check your vitamin D levels. If it's low, s/he can give you a supplement. Having low levels of vitamin D can cause muscoskeletal (I can't spell that word and firefox doesn't recognize it...probably cause it's butchered) pain. On another message board, people recommended cod liver oil to get their vitamin D, but that just sounds really gross to me. Plus, you have to be careful of vitamin A toxicity then depending on much cod liver oil you ingest. (Can I just say bleck.) Just easier to get the pill from the doctor. If you do take vitamin D supplements, you'll want to take calcium supplements, too, I was on high doses of vitamin D supplements and just took a couple of tums a day.
That covered those bases. There are other issues beside DVT that you may want to look at, too. Peripheral artery disease is one that comes to mind.
I do think you should see a doctor. I'm not sure what your Chronic Obstructive Pulmonary Disease (COPD) puts you at increased risk of.
