For the past months, I feel weakness, pains and cramps in both legs that occurs mostly during sleep in the night and sometimes getting up from the bed in the morning.
I've been taking meds., one for High blood pressure and other three different meds. for Arthritis, nerve and leg cramps. All those meds. are in mid-range dosage and a kind 'older meds' that mostly prescribing for long time. Any of meds. are not newly researched meds. as far as I see it.
Strangely, during past winter-time, I didn't take meds. as feeling much better without any pains and cramps whatsoever.
Any insights on this would be greatly appreciated.
How old are you? Maybe it's the lack of movement? Have you suffered an accident lately? There are many possible issues. I experienced weakened legs - it was because I was always staying in front of my computer for a long time, but it disappeared when I would start to walk for a longer time. Try taking some effervescent calcium tablets, they bring strength to the bones. It might not be the solution, but it's worth trying. Go see a medic if you're not confident.
You may be experiencing cramps from calcium or magnesium imbalance (low levels) or anemia. Restless leg syndrome (Willis-Ekbom disease) occurs at night and involves pain, sometimes cramps, but not usually weakness. Pain and weakness could be from muscle inflammation, low potassium. I would see your Dr and ask for the following tests: Serum calcium, magnesium, potassium, ferritin (stored iron-for RLS), blood count, CK (muscle enzyme for inflammation), and BUN/creatinine (kidney problems can cause RLS). I know that is a bunch of stuff, and might be whittled down with a little more clarification on history and exam.
