if your joints dont hurt it the popping isnt really a concern its known as creptitus and everyones joints will pop from time to time
however poor circulation is a concern and should be medically investigated not by ep but by your personal physician so make an appointment soon
RA = Rheumatoid Arthritis --it effects both the joints and muscles and can defunk your heart or circulation at times. I would go into the office to see your primary doctor right away.
It can become serious if left untreated..... I have been dealing with it for 15 years now and it took a good 5 years to find the rights meds for me...... I went into the hospital a few times before the docs managed to get it under control.
Thank you and Hope you feel better soon..... (((hugs)))
I have terrible circulation as well.I wish you both success.
