protein and muscle pain?

My body mass index is 16.5 clearly below average, following health problems I lost 6 kg and especially a lot of muscle
This morning my scale marked 1kg more in a week I am super happy but for 2 days I have pain in the inside of the thigh like aches
I was wondering if it was related to proteins and since I do not can’t do any sport that had to do with these supplements.
If you can clarify this for me, thank you in advance

It can be a bad hydration or a lack of potassium …..
Would have to make a blood test to see.


Me, the lack of potassium, made me have tendonitis.
My doctor, who is a sports doctor, immediately told me that it could be that, which was confirmed by the blood test.
Some have cramps or contractures as a result …
we will see after the assessment but what is strange is that I have already had falls in potassium and it gave me terrible headaches and not cramps.
Just the fact of walking, doing housework with the given protein intake can be aches.
