Additional information: Things were pretty good. Legs hurt little bit when walked a lot, which didn't exist before  Went in and the nurse was concerned about it. Stated he needed to have some protection from this thing. 3 days later, pain again in legs started. Pain didn't feel like legs were being beat or hit with something, but they ached inside. He was toughing it through Taking Advil and Tylenol and all kinds of stuff trying to keep pain under control. Would sleep for 5 hours if he was lucky. States then maybe it will start to wear off, the immune system response is wearing off. Figured if it's not going away, it's getting worse. From what he was reading, in 10 weeks. the immunity to COVID is built up. Thought when the immunity stops building up, maybe the pain will stop then, but it didn't. Started developing twitching in muscle in his legs all the way down to his feet. Almost feels like he had shingles once when he was in his twenties from chicken pox or wherever it comes from. When he goes to walk quite a bit, it feels like the pain is getting the muscle like when had shingles. He talked to a doctor, a neurologist who is retiring and explained what was going on. Neurologist stated what's happening is the antigen from the virus is lodged in muscles in his legs. The nerves are picking up the foreign objects and sending pain signals that something is wrong. Was advised to take Gabapentin 100mg at night and 100mg in morning because it needs to turn the pain off so the sensory nerves will die. This has been going on. Gabapentin does help, but makes him a little groggy. Taking Advil because he believes there's inflammation there. Taking fish oil to relive inflammation. Taking Vitamin C. Caller was speaking to his pharmacist about what the neurologist advised him to do. Pharmacist said eventually it should go and hopefully caller will build sensory nerves back without pain. States it's really strange. He's talked to so many people. Heard many different reactions people have. Nobody is having anything like he is having. Caller was a pro athlete. Never had any particular injuries. Would like to get rid of this problem. He had his 2nd shot on 28Jul2021, he was feeling good, his legs are working okay, he hasn't been able to use his legs a lot because they hurt too much to use for 10 days. After getting the 2nd dose, he didn't feel any reaction for 3 days, but then his muscles and joints begin to hurt again, mainly the hip joints, tinnitus started in his ears, that went on. He's on his 15th week of pain in his legs and it had been getting worse and at around 12 weeks, his muscles and legs began to twitch. Per caller, the Primary Care doctor doesn't have any idea on what medication he should be taking. He's taking Tylenol and Advil, he's also taking Gabapentin for 2weeks. Caller also added that he spoke to his Pharmacist who's giving out Pfizer-BioNTech. He had been having muscle pain now from his hips now to his feet for 17 weeks. He had a lot of leg pain going on from the vaccine. He was desperate after 17 weeks of pain. The provider who was trying to contact us is a neurologist who has him on Gabapentin 100mg, up to 4 a day. A couple of weeks ago his muscles were hurting so bad, that it was incapacitating him and could not walk, and the leg muscles from his hip to his feet were twitching. Most of the twitching has dissipated, but if he walked around too much they start to ache more. He was cutting branches outside before this. He take one of our products Advil, he took 1 to 3 a day, and it helps a lot. Tylenol does not touch it. He took 200mg of Gabapentin today and will take another 100mg at 11:30 at night when he went to bed. His own doctor who has been his doctor for 25 years. He took fish oil, he spoke to an advisor, and he recommended fish oil which he was up to 7000mg a day now, and turmeric is very good antioxidant for inflammation. The doctor was looking for medications that may be given to people with muscle pain, because he says about 14 to 15 percent of people have this problem, but maybe not as long as him.
