<s>[INST] i HAVE BEEN HAVING DEEP MUSCLE PAIN WHERE I COULD NOT WALK FOR OVER A YEAR. I CAME UP ANEMIC AND STARTED TAKING IRON PILLS. I WAS ONLY ANEMIC @ 37 WHEN THE AVERAGE FOR WOMEN IS 36 TO 45. HOWEVER, THE PILLS DID WORK. WHEN I EXERCISE MY PAIN COMES BACK AND I NEVER REGAINED STRENGTH IN MY ARMS AND MY LEGS. I CAN EXERCISE A LOT & I WILL STILL BE WEAK. MY LOWER BACK HURTS A LITTLE. I AM STILL VERY TIRED ALL THE TIME. [/INST] Hello, I read carefully your query and understand your concern. Your symptoms seem to be related to anemia. I see that you have already taken iron supplements to treat these diagnose. I recommend continuing this medication at least for 3-months. After this period of time I recommend repeating the complete blood count check if the treatment was effective. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.  </s>
