I have hard red painful marks ALL OVER my legs. like probably today 20 to 25 on each leg yesterday probably 15 to 20.... they probably started 2 weeks ago with only 3 on my lower left leg. but in the last 5 days they have spead up both legs and they are VERY VERY PAIN-FULL . but before the red bumps started on my right leg only my rt knee was painful, solid red and even had fever. now this evening more painful red dot/ bumps{they are like hard under the skin???} on my legs and both knees are now swollen red and have fever. and my ankles are 3 times their size!!!
In my opinion you have a viral infection, HIV or Lyme I recommend you see a doctor immediately , the earlier the treatment the better Good Luck
