Iwhat have had increase arthritic pain,chills,sweats,weakness, fatigue,headach,mild sorethroat,mild cough,sinus like infection. After 2 or three weeks it seems to go away but keeps coming back. About 30 years ago I had a bulls eye bite on my back and also had scarlet fever as a child. I am in constant pain from arthritis. My hip is bone on bone and said to be osteoarthritis. What do you think could help the constant flu like symptoms. Also what would help arthritis pain. (I have high blood pressure and family heart problems).
