My boyfriend does a lot of weight lifting and decided to take glucosamine sulphate for joints. After 3/4 days of taking them he began to get shoulder pains. He stopped taking the supplement and is still suffering. He now is kept awake at night with severe back pain and shoulder pain. Went to GP who just said see how you go after a couple of weeks and come back which is no help. He had acupuncture which eased the pain for about an hour but went back to being in agony. We did a bit of research and discovered that you shouldnt take the supplement if allergic to shellfish and he is allergic to mussells. But this does not seem like an allergic reaction. Also i think he may be diabetic as for the past year i have never known anyone to urinate so frequently. He gets up about 3 times in the night and every hour or so in the day. When he drinks a lot he urinates every 10/15 minutes!!! Can anyone advise as to why his pain is happening only after taking glucosamine sulphate! Please, he is agony!

I am in good shape and good health, but in my family arthritis and the likes are genetically present. As the years pass I feel more and more soreness and pain, mostly in my fingers, but lately my shoulder started to hurt. I am not taking any specific medicine and try to work out 5 times a week, some leight weight lifting and also some cardio. I am not overweight and try to eat reasonably.
A friend of mine suggested taking Glucosamine tablets to help reduce pain and prevent further problems.
Any suggestions? Personal experience?
Thxs a lot in advance.
