Dear there, Thanks for registering in Health care majic. these joint pains are required a detail clinical assessment to rule out the cause. As per the present complaints are concerned knee pain is suggestive of meniscal sprain/ tear and shoulder pain is impingement syndrome. In both the cases cryo pack for 15 minutes will give you immediate relief.. Pulsed mode ultrasound therapy helps in promotong the healing process. take some NSAID(non steroidal anti inflammatory drugs)..... Kinesiology taping technique by a cerified sports physio gives you amazing result....... A detail clinical assessment by clinical tests and investigations like X ray/MRi (if required) will give more accurate findings about the cause of the pain and proper diagnosis. Wish you get rid out of the pain soon....
